Question

Horace read 160 pages in 4 hours. How many pages can he read in 6 hours??

Answer 1

160/4 = p/6

Cross-multiply the propportion:

160 x 6 = 4p

Divide each side by 4:

p = 40 x 6 = 240 pages

Answer 2

You do 160/4 to find one pages time.

This is 40 pages.

Then you do 40 x 6 to find pages in 6 hours
