An inlet pipe on a swimming pool can be used to fill the pool in 22 hours. The drain pipe can be used to empty the pool in 33 hours. If the pool is 13 filled and then the inlet pipe and drain pipe are opened, how long from that time will it take to fill the pool?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
