a person reads 15 pages in 45 minutes how many pages can he read in 2 hours

Answer 1

2 hours means 120 minutes, and then you can find out how many minutes it takes to read one page.

15 pages/45 minutes means 1 page is read every 3 minutes.

You can now multiple this fraction, (1 page/3 min) by 120 min, giving you 40 pages

Answer 2

Set up the proportion 15/45 = x/120. Cross multiply and solve. You get 40 pages!
