Question 720114: John can dig the garden in 40 minutes while Jane can dig the garden in 25 minutes. How long will it take to dig the garden together? Answer by god2012(113) (Show Source):
You can put this solution on YOUR website! work done by John in 1 min = 1/40
Work done by jane in 1 min = 1/25
work done by both in 1 min = 1/40 + 1/25 = 9/200
Therefore total time taken = 200/9 mins = 22.222 mins
