Question

It takes Jack 11 hours to pick 40 bushels of apples alone. Jill can pick 40 bushels of apples in 9 hours. How long will it take Jack and Jill to pick 40 bushels of apples together. Round to the nearest hour.

Answer 1

5 hours

Explanation:

Jack 40/11 = 3.64 bushels per hour

Jill 40/9 = 4.44 bushels per hour

together they pick 3.64 + 4.44 = 8.08 bushels per hour

40/8.08 = 4.95 hours
