...
jim can fill a pool- 30 minutes
sue can do the same in 45 minutes,
Tony can do the same job in 1 1/2 hour. =90 minutes
...
jim does 1/30 of job in 1 minute
sue does 1/45 of the job in 1 minute
Tony can do 1/90 of the job in 1 minute
..
Together they can do
1%2F30+%2B1%2F45+%2B1%2F90 of the job in 1 minute
LCD = 180
...
+%286%2B4%2B1%29%2F180
=11%2F180
so they can do the job in 180%2F11 minutes
