He had to read 12 pages a day, which would take him 15 days to finish. If he finished the book five days earlier, how many pages would he read every day?
It would take 15 days to finish reading 12 pages a day. How many pages would you read if you finished the book five days in advance? If the book has 100 pages and you read 12 pages a day, the number of days it takes to read the whole book is: 100 pages/12 pages/day = 866 days Because the book needed 15 days to finish, it clearly needed 15-866=634 days. In these 634 days, he had to read 12 pages a day to finish the book five days earlier. Therefore, if you finish this book five days in advance, how many pages do you read every day: 12 pages/day x 634 days = 792 pages Therefore, he had to read 792 pages a day to finish the book five days earlier.
A book had 62 pages. If he had to finish it in 12 days, how many pages would he write every day?
There are 62 pages in a book that need to be written in 12 days. The answer can be obtained by calculating how many pages you need to write each day. 62 pages/12 days = 5 pages/day Therefore, he had to write five pages a day. Please note that this is only an estimate. The actual writing speed may be affected by many factors such as the quality of the writing, the length of the article, etc.
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.
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.
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.
Little Ming was reading a book with a total of 200 pages. In the first five days, he had read half of the book. In the future, he would read five more pages every day. How many more days would it take to finish?
Xiao Ming read this book, which had a total of 200 pages. In the first five days, he read half of the book, which was 1/2 * 5 = 5 pages. In the future, he would read five more pages every day, so the number of pages he read every day was half of the original number of pages, which was 1/2 * 5 = 5 pages. Therefore, the number of days needed for Xiao Ming to finish reading this book was: 200 ÷ (1 + 5/2 + 5) = 200 ÷ (1 + 10) = 10 Therefore, Xiao Ming needed 10 days to finish reading this book.
Ding Ding read a book. On the first day, he would read 15 pages. After that, he would read five more pages every day than the previous day. After five days, he would finish reading. How many pages does this book have?
Assuming that the book has x pages: 15 pages on the first day, so there are 15 pages in the book From now on, I'll read five more pages every day than the day before, so after five days, I'll read (15+5)×5=125 pages, plus the 15 pages I've already read before, that's a total of 270 pages Therefore, the book had a total of 270 pages.
If Xiao Sen read 30 pages a day, he could finish it in 20 days. If he wanted to finish it in fifteen days, he would have to read forty pages a day.
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.
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.
Xiao Ming read a book. He read 72 pages in the first 4 days and 29 pages a day for the next 6 days. How many pages did he read on average every day?
If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 pages a day.
