Jim can fill a pool carrying buckets of water in 30 minutes. Sue can do the same job in 45 minutes. Tony can do the same job in 1 ½ hours. How quickly can all three fill the pool together?
--------------------
Jim does 1/30 of a pool per minute
Sue does 1/45
Tony does 1/90
--------------
Per minute, it's 1/30 + 1/45 + 1/90 = 6/90 = 1/15 pool per minute.
15 minutes
