An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. the drain pipe can be used to empty the pool in 34 hours. if the pool is 1/3 filled and than the inlet pipe and drain pipe are opened how long would it take to fill the pool

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs

Solution:

Let x = time it will take to fill the pool

= work rate of inlet pipe

= work rate of drain pipe

Using the formulae

Volume of flow=work rate time

Let us assume complete time of pool to fill = 1

Remaining fraction of pool to be filled =

Time it will take to fill the pool = 748 hrs

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

answer: -8.2562234e+13
