Argyle can read 7 pages of his book in 5 minutes. At that rate, how many pages can he read in two hours?

Question

Need an equation

Answer 1

2 hours=120 minutes

set up a proportion

7 pages/5 minutes=n pages/120 minutes

7/5=n/120

(7)(24)/(5)(24)=168/120 so n=168 pages

also...

cross multiply

5*n=7*120

5n=840

n=840/5

n=168 pages
