I can cut a yard in 3 hours. You can cut the same yard in 2 hours. If we did the yard together how long would it take us?

Answer 1

Your work rate is 1/3.

My work rate is 1/2

Our combined work rate is 1/3 + 1/2 = 5/6

Working together, we cut the yard in 6/5 hour = 1 and 1/5 hour = 1 hour 12 minutes
