Little Light started reading a novel on January 5th. If he read 80 more pages a day, he would finish it on January 9th. If he read 90 pages a day, he would finish it on January 8th.
If Little Light started reading a novel on January 5th, he would finish it by January 9th, and if he read 90 pages a day until January 8th, then what day would Little Light finish it? Assuming that the number of pages in the novel is X, then the number of pages Little Light reads every day is X+80, then the total number of pages he needs to read is (X+80)×28 days. (X+80)×28 = X×28 + 80×28 To simplify it: X = 5200 Therefore, the number of days Little Light needed to finish reading could be calculated by the following equation: (5200+80)×28 = 5200×28 + 80×28 504000 = 104000 Little Light needed to finish reading on the 104th day.
Wang Liang started reading a novel on January 5th. If he read 80 pages a day, he would finish it on January 9th. If he read 90 pages a day, he would finish it on January 8th.
If Wang Liang reads 80 pages a day, he will be able to finish the first part of the novel by January 9th. If Wang Liang reads 90 pages a day, he will be able to finish the first part of the novel on January 8th, but he will need an extra two days to finish the whole novel. Therefore, if Wang Liang started reading a novel on January 5th, he would need an extra five days (January 9th to January 14th) to finish reading the entire novel.
Little Light started reading a novel on January 5th. If he reads eighty pages a day, he will finish it by January 9th; if he reads ninety pages a day, he will finish it by January 8th...
If Little Light started reading 80 pages a day from January 5th, he would need to finish 1/8 of the novel on the 10th day. Therefore, Little Light needed to finish reading the novel on January 12th. If Little Light read 90 pages a day, he would need 16 days to finish 1/8 of the novel, which was 120 pages. Therefore, Little Light needed to finish reading the novel on January 16th.
He was going to read a 158-yuan story book, but he read 16 pages a day. If he started from July 25th to August 3rd, would he be able to finish reading it?
The total number of days required to finish reading a 158-page storybook is: 158 pages/16 pages/day = 105 days There were 30 days from July 25th to August 3rd, so: 30 days/105 days/day = 2875 Because the total number of pages per day was 16, so: 158 pages/16 pages/day = 105 days Therefore, he had to read 16 pages a day from July 25th to August 3rd to finish the 158 pages of the storybook.
Li Xiaolin was reading a storybook. If he read 12 pages a day, he would finish it in 15 days. If he had to finish it in 10 days, how many pages should he read on average every day?
If you can finish a storybook by reading 12 pages a day and 15 days, then the average number of pages in this storybook is: 15 days/ 12 pages/day = 15 pages/day Therefore, if Li Xiaolin wanted to finish reading this storybook in 10 days, he should read it on average every day: 10 days/ 15 pages/day = 6 pages/day In other words, Li Xiaolin should read 6 pages a day instead of 12 pages a day.
Xiao Ya planned to finish reading a book in 20 days and read 15 pages a day. If he read five more pages a day, how many days would he be able to finish it?
If he read five more pages per day, the total number of pages per day would be 15 * 5/5 = 30 pages. The total number of pages that Xiao Ya needed to read in 20 days was 30 * 20 = 600 pages. If you read 15 pages a day, the total number of pages you need to read is 600 * 15/15 = 600 pages. Therefore, if you read five more pages a day, you can finish the book faster. The answer was: Ya-chan could finish the book in 15 days. She could read five more pages a day, and a total of 30 more pages, so she only needed 20-15=5 days to finish it.
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.
Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. Based on this information, we can formulate the following equation: Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day. Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions: Xiaoming finished reading the novel before the stipulated date 2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days Therefore, we can write the following equation: x/35 = (x/12) - 1 Solve the equation: x = 35x/12 + 1 = 40 Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
A novel had 404 pages. He read an average of 40 pages a day. How many days would it take to finish reading?
If a novel has 404 pages and you read an average of 40 pages a day, you can calculate how many days it takes to finish it. 404 pages/40 pages/day = 102 days Therefore, it would take about 102 days to finish a 404-page novel.
If Little Ming reads a book, if he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads a book every day for 15 pages and 24 days, then the book has a total of 15 * 24 = 360 pages. If I read 20 pages a day, how many days can I finish it? Assuming that the book has x pages, the total number of pages that Xiaoming needs to read is 20 * x days. Because Xiao Ming needed to read 360 pages, there were: 20 * x = 360 Solve this equation: x = 180 Therefore, Xiao Ming needed to read 180 pages to finish the book. If he read 20 pages a day, he would need 180 * 20 days = 3720 days to finish the book.
Xiao Ming planned to read a novel every few days. If he read 60 pages a day, he could finish it five days earlier. If he read 40 pages a day, he would have to finish it three days later.
Xiao Ming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. Calculating how much faster reading 60 pages a day was than reading 40 pages a day: Reading 60 pages a day is better than reading 40 pages a day, reading 40 pages per hour, 60 pages = 067 hours Therefore, the total time Little Ming needed was: 1/067 = 1667(hours) 5 days ago 1667/067 = 28(hours) Days of delay Therefore, Xiao Ming needed 28 hours to finish reading this novel, which was longer than expected. Next, we can calculate the ratio of reading 60 pages a day to reading 40 pages a day, reading 40 pages per hour, reading 60 pages = 067 hours 's progress: Reading 60 pages a day is better than reading 40 pages a day. Reading 60 pages per hour/40 pages = 15 hours Therefore, the total time Little Ming needed was: 1 × 15 = 0667(hour) 5 days ago 0667/15 = 04(hours) Days of delay Therefore, Xiaoming needed four hours to finish reading this novel, which was shorter than the estimated time. To sum up, Xiaoming plans to read a novel every few days. If he reads 60 pages a day, he can finish it five days earlier. If he reads 40 pages a day, he will finish it three days later. If reading 60 pages a day was faster than reading 40 pages a day, reading 40 pages per hour, reading 60 pages per hour = 067 hours, the total time required was 1667 hours; if reading 60 pages a day was slower than reading 40 pages a day, reading 60 pages per hour, reading 60 pages per hour = 15 hours, the total time required was 0667 hours.
A 600-page storybook. Nono would read 28 pages a day. Could he finish it in 19 days?
Reading 28 pages a day in 19 days can finish a 600-page storybook, but you need to pay attention to the following points: 1 The total number of pages in a storybook is 600, and reading 28 pages a day is actually only 28/2 = 14 days to finish reading each page. Therefore, he needed to divide 19 days by 14 days to determine the total number of pages he could read. The answer was that they could finish reading it, but they needed more time. If you read 28 pages a day, you would need 14 days to finish the story book. If Nono only reads 1 page in the remaining 14 days, she will not be able to finish the storybook. Therefore, Nono had to ensure that he could read a certain number of pages every day to ensure that he could read the entire story book. Reading 28 pages a day would take 14 days to finish a 600-page storybook. In the remaining 14 days, he had to ensure that he could read a certain number of pages every day in order to read the storybook completely.
