I need someone smart please; Ashley is wanting to fill her pool for the summer. Her hose will fill the pool in 4 hours. There is a small leak in the pool that would drain a full pool in 120 hours. How long would it take her to completely fill the pool?

well, you need to compare two rates. if you know you can fill a pool in 4 hours, that means you can fill 1/4 pools per hour BUT you are losing water at the rate of 1/120 pools per hour. So, the net amount in is that difference, (1/4-1/120) pools per hour. But the problem asks about hours per pool, so you take the reciprocal and get approx. 4.14

its a matter of subtracting rates: rate In = 1 pool every 4 hrs rate Out = 1 pool every 120 hrs Net rate = 1/4 - 1/120 = 30/120 - 1/120 = 29/120 Rate * time = 1 pool time is reciprocal of rate --> 120/29 = 4.138

That makes a little more sense. Thanks
