Question 143539: Problem: Recovering golf balls. Susan and Joan are diving for golf balls in a large water trap. Susan recovers a golf ball every 0.016 hour while Joan recovers a ball every 0.025 hour. If both are working, then at what rate (in golf balls per hour) are they recovering golf balls?

You can put this solution on YOUR website! Susan's rate + Joan's rate = Rate working together
In words:
(1 golfball / .016 hrs) + (1 golfball / .025 hrs) = (x golfballs / 1 hrs)

They are recovering 102.5 golfballs per hr working together
