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.
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.
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.
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.
If Xiao Sen read 30 pages of a literature book every day for 20 days, he could finish it. If he needed to read 40 pages a day to finish it in 15 days, then his reading speed should be 10 pages more per day. The calculations were as follows: 20 days x 30 pages/day = 600 pages 15 days x 40 pages/day = 600 pages Reading 10 more pages per day, the total number of pages required is 600 pages/(30 pages/day + 40 pages/day) = 600 pages/70 pages/day = 88 days Therefore, Xiao Sen needed to read 10 more pages every day, which was about 88 days, to finish reading this literary book.
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.
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.
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.
According to the description of the question, Liu Qiang read 30 pages on the first day, then he read 30+3=33 pages on the second day, 33+9=42 pages on the ninth day, 42+12=54 pages on the tenth day, and 60 pages on the eleventh day. Therefore, Liu Qiang read 60 pages on the 11th day. The answer is: Liu Qiang read 60 pages on the 11th day.
Xiao Hong reads a 298-page storybook, 24 pages a day. It is estimated that he will start reading from August 20th to September 1st. Can he finish reading this book before school starts? Yes, Xiao Hong could finish reading this book before school reopened. Reading 24 pages a day would take nine days, which was 292 pages. The total number of pages in the storybook was 298, so Little Red needed to read 292 pages in these 9 days. As she reads 24 pages a day, Little Red can finish reading in 9 days and does not need to rest or rest. Therefore, Xiao Hong could finish reading this book before school reopened.
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.
