Susan and Joan are diving for golf balls in a large trap. Susan recovers a golf ball every 0,016 hours 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:
Time = 0.016 hrs/job ; Rate = 1/0.016 job/hr
-------------------
Joan DATA:
Time = 0.025 hrs/job ; Rate = 1/0.025 job/hr
------------------------
Their together rate is 1/0.016 + 1/0.025 = 62.5 + 40 = 102.5/hr
