Susan and Joan are diving forgolf 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's rate: 1 golf ball per .016 hr: 1/.016
Joan's rate: 1 golf ball per .025 hr: 1/.025
.
If they were to work together, the rates are combined:
1/.016 + 1/.025
= .025/.0004 + .016/.0004
= .041/.0004 balls per hour
or 102.5 balls per hour
