Li Ming was reading a 225-page novel. For the first five days, he would read 24 pages a day, and then 35 pages a day. How many more days would he need to finish this novel?
Li Ming read a 225-page novel. For the first five days, he read 24 pages a day and then 35 pages a day. The calculation is: 100 pages in the first 5 days, the remaining pages are 225-100=125 pages. Reading 24 pages a day required 125/24=5 days. Reading 35 pages a day required 125/35=4 days. Therefore, Li Ming needed 5+4=9 days to finish reading this novel.
Xiao Ming read a 480-page storybook and read page A every day for 12 days. How many pages are left?
When Xiao Ming read page A of the storybook every day for 12 days, he had read a total of 12 × page A. Therefore, when Xiaoming reads a 480-page storybook, he still has 480 - 12 × a pages left. To calculate the remaining pages, he needed to know how many pages Xiao Ming read in the end and how many pages he read every day. If we assume that the last page that Xiao Ming read was 480 pages and he reads page a every day, then we can write the following equation: 480 - 12 × a = Remaining pages By solving this equation, we can get: Remaining pages = 480 - 12 × a = 480 - 12a Therefore, after reading page A for 12 days, Xiao Ming still had 480 - 12A pages left.
18 pages a day, 14 days to read and play. If you finish reading it five days in advance, how many pages should you read every day?
If you read 18 pages a day, it would take you 14 days to finish it. If you want to finish the book 5 days earlier, you need to shorten the number of days to 10 days. 5 days earlier is equivalent to reading 18 pages less per day, so you need to read 24 pages per day (14 days-5 days =10 days).
Little Ming had been reading a 330-page novel for six days. He read an average of 20 pages a day. How many pages would he read in the remaining seven days?
Xiao Ming borrowed a 500-page novel and read 280 pages in the first 5 days. How many pages did he read on average every day?
Xiao Ming had read 280 pages in the past 5 days, so he had already read 280 x 5 = 1400 pages. The book has 500 pages, so the remaining pages are 500 - 1400 = -700 pages. This means that Xiaoming has to reread the 700 pages of the book in the next 7 days, but he can choose to start reading on any day. If Xiao Ming chose to start reading from the sixth day, then the number of pages he needed to read every day was 700/6 = 100 pages. Therefore, Xiao Ming needed to read 100 pages on average every day.
Xiao Ling read a 290-page novel. For the first four days, she read 20 pages a day. From now on, he would be able to finish reading 30 pages a day in a few days.
You can use the following formula to calculate the number of days it will take Xiao Ling to finish reading this novel: Days = total page count/page count for the first 4 days + 1(add 1 day later) Total pages = 290 pages The number of pages read in the first 4 days = 20 pages/day × 4 days = 80 pages/day Therefore, the total number of pages that Xiao Ling needed to read was 290, and she had read 80 pages a day for the first four days, totaling 480 pages. Next, Xiao Ling needs to read 30 pages/day in the next day, so she still needs to read 480 pages/30 pages/day = 16 days Therefore, Xiao Ling needed 16 days to finish reading this novel.
Xiao Ming read a book with 240 pages. He had already read 4 pages. On average, he would read 15 pages a day. Which page would Xiao Ming start reading on the fifth day?
Xiao Ming read an average of 15 pages a day. He had already read 4 pages, so he still needed to read 4/15 = 02 days. Because Xiao Ming needed to watch for 5 consecutive days, he could move the days that he needed to watch forward by 5 days. 2 days + 4 days = 6 days Therefore, Little Ming needed to start from page 6, which was page 11.
Xiao Ming was reading a 256-page book. He had been reading 13 pages a day for seven days. He had to calculate how many pages he had not read.
How many days has Xiaoming been watching? (Question symbol) I've been reading for seven days, so I haven't read seven pages. The remaining pages were 256 - 13 × 7 = 234 pages. Therefore, Little Ming still had 234 pages to read.
Xiao Dong read a 420-page book. He read 26 pages a day. After reading for 13 days, how many pages were left?
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.
Little Ming read a book. He read 15 pages in the first 4 days and 6 pages a day in the next 5 days. How many pages did he read on average every day?
Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three pages a day.
