Respuesta :

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
