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.
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 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.
Xiao Ming planned to read 36 pages a day, but he actually read 500 pages in 12 days. How many more pages did he actually read per day?
Xiao Ming planned to read 36 pages a day, but in fact, he read 500 pages in 12 days. 500 pages/12 days = 40 pages/day Because Xiao Ming reads 36 pages a day, the actual number of pages should be 40 pages more than the plan: 40 pages/day- 36 pages/day = 4 pages/day Therefore, Xiao Ming actually read four more pages of novels every day.
If Xiao Lin read 30 pages a day, he could finish it in eight days. If Xiao Lin wanted to finish it in six days, how many pages would he have to read on average every day?
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.
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.
A book had a total of 260 pages, and Xiao Ming had already read 80 pages. He had to finish the rest in five days. How many pages did he read on average every day?
Xiao Ming needed to finish reading the remaining 260 pages in 5 days, so he needed to read 260 pages per day divided by 5 days = 52 pages.
Xiao Lin read a literary masterpiece. If he read 30 pages a day, he could finish it in eight days. If Kobayashi wanted to finish it in six days, how many pages would he have to read on average every day?
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.
Xiao Lin read a literary masterpiece. If he read 30 pages a day, he could finish it in eight days. If Kobayashi wanted to finish it in six days, how many pages would he have to read on average every day?
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.
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.

Uncle Wang planned to finish reading a 217-page novel in 15 days. He read a total of 112 pages in the first 8 days. How many pages does he read on average every day? Uncle Wang had read 112 pages in the first 8 days, so the total number of pages he needed to read in the remaining 15 days was: 15 days x 112 pages/day = 1656 pages Since he planned to finish the book in 15 days, the total number of pages he needed to read had to be a whole number. Therefore, he needed to divide 1656 pages by 15 days to get: 1656 pages/15 days = 104 pages/day For the remaining 15 days, Uncle Wang needed to read 104 pages a day.
