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.
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.
Reading 30 pages a day in 8 days would allow one to finish reading this literary masterpiece. 30 pages/day x 8 days = 240 pages If Kobayashi wanted to finish it in six days, the total number of pages he needed to read was: 240 pages/6 days = 40 pages/day As a result, Kobayashi read an average of 40 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.
Assuming that this literary masterpiece had 1000 pages, Kobayashi could read 30 pages a day, so he could read 320 pages in eight days. If Kobayashi wanted to finish it in six days, the total number of pages he needed to read was: 1000 pages/6 days = 16667 pages/day Since there is no prime number difference between reading 30 pages per day and reading 16667 pages per day, we can assume that Kobayashi reads 167 pages per day. In this way, the total number of pages of literary classics that Xiao Lin needed to read in six days was: 167 pages/1 day = 167 pages Therefore, Kobayashi needed to read 167 pages a day to finish reading this literary masterpiece in six days.
Assuming that this literary masterpiece has $N$pages, Kobayashi has to read it in 6 days, so the total number of pages needed is $N$. Reading $30$pages a day meant that Kobayashi could read $30/times 6 = 180$pages in 6 days. In order to find out how many pages Kobayashi reads on average every day, we can divide the total number of pages by the total number of days: $$ \frac{N}{8} = \frac{180}{8} = 25 $$ As a result, Kobayashi read an average of $25 per 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.
Reading 28 pages a day in 19 days can finish a 600-page storybook, but you need to pay attention to the following points: 1 The total number of pages in a storybook is 600, and reading 28 pages a day is actually only 28/2 = 14 days to finish reading each page. Therefore, he needed to divide 19 days by 14 days to determine the total number of pages he could read. The answer was that they could finish reading it, but they needed more time. If you read 28 pages a day, you would need 14 days to finish the story book. If Nono only reads 1 page in the remaining 14 days, she will not be able to finish the storybook. Therefore, Nono had to ensure that he could read a certain number of pages every day to ensure that he could read the entire story book. Reading 28 pages a day would take 14 days to finish a 600-page storybook. In the remaining 14 days, he had to ensure that he could read a certain number of pages every day in order to read the storybook completely.
The rest of the books had to be finished in five days, so he had to read 125 pages a day.
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.
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.
