Question 197218: If Sally can paint a house in 4 hours, and John can paint the same house in 6 hour, how long will it take for both of them to paint the house together? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Sally does 1/4 the job in 1 hr.
John does 1/6 the job in 1 hr.
Together: 1/4 + 1/6
=3/12 + 2/12
5/12 of the job done in 1 hr
12/5 hrs to do the job together.
