Question

Tommy can paint a fence in 14 hours. If his friend Huck helps, they can paint the fence in 1 hour. How fast could Huck paint the fence by himself?

Answer 1

Answer: Huck can paint the fence in 14/13 hours or 1.077 hours

Explanation:

The formula for the shared work problem is 1/f + 1/g = 1/A

1/14 + 1/g = 1

1/g = 1 - 1/14 = 13/14

g = 14/13 hours
