If I read 30 pages a day, I can finish it 10 days earlier. If I read 15 pages a day, I can finish it 10 days later
The time spent reading a book depends on the number of pages you read each day. Reading 30 pages a day is 10 days slower than reading 15 pages a day. So if we were to read 30 pages a day, we would need to spend an extra 10 days on top of the original 10 days to finish the book. On the contrary, if we read 15 pages a day, we would need to spend an extra five days on top of the original 10 days to finish the book. So we can finish the book ten days earlier or ten days later, depending on the number of pages we choose to read and our reading speed.
Doudou would read 12 pages a day, and he could finish it in seven days. If I finish it in six days, how many pages will I read per day?
If Doudou could finish a book by reading 12 pages a day in 7 days, then the total number of pages would be: 12 pages/day x 7 days = 96 pages Therefore, the number of pages that Lil Pea needed to finish reading this book in six days was: 96 pages/6 days = 16 pages/day Therefore, Doudou had to read an average of 16 pages a day.
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.
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.
There are 170 pages in a book. I have read 45 pages. I have to finish the rest of the book in 5 days. How many pages do I read per day on average?
The rest of the books had to be finished in five days, so he had to read 125 pages a day.
There are 170 pages in a book. I have read 45 pages. I have to finish the rest of the book in 5 days. How many pages do I read per day on average?
The rest of the book had to be finished in the next five days, so he had to read 170 pages in total. I have already read 45 pages, so I need to read 125 pages a day (170 pages/5 days). Therefore, he read an average of 125 pages a day.
The storybook I borrowed has a total of 119 pages. I read 39 pages in the past three days. Can I finish it in a week? If I want to finish it on time, from the fourth day onwards, I'll read it on average every day.
It depends on the total number of pages of the storybook you borrowed and the average number of pages you read every day. If you borrowed a storybook with a total of 119 pages and read 39 pages in the past three days, then there are still 80 pages left to read. There are seven days in a week, so you need to read an average of 14 pages a day out of the 80 pages to finish reading on time. If you want to finish it on time, you need to read an average of 15 pages a day from the fourth day onwards.
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).
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 book is fifty pages thick. I read five pages a day. How many days does it take to finish reading it?
A book that was 50 pages thick, reading five pages a day meant that he could read 15 pages per hour. If a book was 50 pages thick and required a few days to finish, then it would take 5 * 60 / 15 = 24 days. Therefore, if one were to read five pages a day, it would take 24 days to finish a book that was 50 pages thick.
