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?

Best ResponseYou've already chosen the best response.0well, 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, (1/41/120) pools per hour. But the problem asks about hours per pool, so you take the reciprocal and get approx. 4.14

Best ResponseYou've already chosen the best response.0its 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
