For a book, if he had read 170 pages in the first 10 days, at this speed, he would be able to finish it in another 8 days. How many pages was this book?
Assuming that the book has a total of x pages, then based on the 170 pages read in the previous 10 days, we can get: Day 1 - 10 days = 170 pages Day 2 - 11 = 180 pages Day 3 - 12 days ago = 190 pages Day 10-First 10 days = 170 pages Therefore, the book had a total of x pages that could list an equation: x = (170 + 180 + + 190) / 10 To simplify it: x = (1700 + 190n) / 10 Where n was the number of pages read on the 10th day. Because on the 10th day, I watched it for 8 days, so there were: n = 8 Substituting n into the above formula: x = (1700 + 190*8) / 10 x = (1700 + 1564) / 10 x = 2264 Therefore, this book had a total of 2264 pages.
A storybook had 600 pages, but he had read 130 pages in 5 days. At this speed, how could he finish reading it in 25 days?
At this rate, he could finish reading 600 pages in 25 days. However, due to the number of pages read each day, the specific reading time may vary. Assuming that the number of pages read per day is 130, then the number of pages that can be read in 25 days would be: 25 days x 130 pages/day = 3350 pages Therefore, he needed to spend 25 days to finish reading all 3350 pages of the story book. It is worth noting that this is only a hypothesis. The actual reading speed may be affected by many factors, such as the difficulty of reading, the number of pages read, the mood of reading, and so on.
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.
Little Light read 192 pages in three days, and he read 72 pages in three days. How many days can he finish reading at this speed?
Assuming that each page of the novel is 250 words long: 192 pages/250 words/page = 72 days Therefore, it would take Little Light 72 days to finish a 192-page novel at a rate of 72 pages a day.
There were 150 pages in a book, and he had already read 38 pages. How many pages would he read in the remaining seven days?
He had already read 38 pages, so the remaining pages were 150 - 38 = 112 pages. In order to finish reading these 112 pages, he had to read 112/7 = 16 pages every day. Therefore, he read an average of 16 pages a day.
A science book had 32 pages. After reading 8 pages, he would finish it in the remaining 4 days. How many pages did he read per day?
To read the remaining 4 books, Naughty needed to read 32-8=24 pages. Therefore, she needed to read 24/4=6 pages every day. So, on average, Naughty reads six pages a day.
Xiao 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 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
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.
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.
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.
