Question

Kevin wrote a total of 12 pages over 3 hours. How many hours will Kevin have to spend writing this week in order to have written a total of 20 pages? Assume the relationship is directly proportional.

Answer 1

5 hours

Explanation:

For 12 pages, he spent 3 hours. So it takes him 1 hour to write 4 pages. (12 ÷ 3 = 4) If for each 4 pages 1 hour is spent respectively, then for 20 pages: 20 ÷ 4 = 5 hours will be spent.

Answer 2

It will take him 5 hrs to write a 20-page essay because he can write 4 pages in 1 hour.

Hope this helps!
