Question

Payton wrote a 4-page paper in 5 hours. How long would it take for her to write a 7-page paper?

Answer 1

8.75 hours

Explanation:

We can use ratios to solve. Put the pages over the time and set them equal.

4 pages 7 pages

------------- = ---------------

5 hours x hours

Using cross products

4 * x = 5 *7

4x =35

Divide by 4 on each side

4x/4 = 35/4

x =8.75 hours
