You can put this solution on YOUR website! F.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?
-----------
Susan DATA
rate = 0.016 ball/hr
----------------
Joan DATA:

0.016 + 0.025 = 0.41 ball /hr
