Question 1064590: An Olympic sized pool can be filled by pipe a in 18 hours and pipe b in 12 hours.there is also a drain pipe that drains the entire pool in 8 hours. if the values of pipe a and pipe b and the drain pipe are open how long will it take to fill the pool? round to the nearest tenth of an hour if necessary.
rate, time, fraction of job Found 2 solutions by josgarithmetic, ikleyn:Answer by josgarithmetic(39617) (Show Source):
The pipe A fills of the pool volume per hour.
The pipe B fills of the pool volume per hour.
The pipe C drains of the pool volume per hour.
When all 3 pipes work, they fill = of the pool volume per hour.
Hence, it will take 72 hours to fill the pool if all 3 pipes are open.
