A 450 gallon water tank is leaking at a rate of 20gallons per hour. Approximately, how long will it take to completely fill the tank if a hose is continuously running water into the tank at a rate of 15gallons per minute and if the tank already has 50gallons of water?

HI...
I think the answer is 300/11 minutes. This will take to completely fill the tank.
20 gallons per hour = 1/3 gallons per minute
THen the tank received 15 gallons in a minute and lost, at the same time, 1/3 gallons in a minute.
15 - (1/3) = (44/3) The tank received finally 44/3 gallons per minute.
If the tank has 50 gallons, we need to put in the tank, 400 more gallons, to fill it.
Thus, the tank receives in one minute 44/3 gallons, how long it will take to get 400 gallons?
...............................300/11 minutes.....
