Answer:
4 pages per hour
Step-by-step explanation:
Willie and Pedro are reading the same book. Willie read 108 pages in 3 hours, and Pedro read 160 pages in 5 hours.
We find how many pages per hour each of them read.
For Willie
Willie read 108 pages in 3 hours,
3 hours = 108 pages
1 hour = x
Cross Multiply
3x = 108 pages × 1 hours
x = 108 pages/3
x = 36 pages per hour
For Pedro
Pedro read 160 pages in 5 hours
5 hours = 160 pages
1 hour = x
Cross Multiply
5x = 160 pages × 1 hours
x = 160 pages/5
x = 32 pages per hour.
How many more pages per hour did Willie read?
This is calculated as:
36 pages/hour - 32 pages per hour
= 4 pages per hour
