Question 369648: While pipe A can fill a tank in 3 hours, pipe B can take out a full tank in fours. A full tank fits 360 gallons of water. If both pipes are turned on at the same time, how many gallons of water would be in the tank in 6 hours?

You can put this solution on YOUR website! While pipe A can fill a tank in 3 hours, pipe B can take out a full tank in fours. A full tank fits 360 gallons of water. If both pipes are turned on at the same time, how many gallons of water would be in the tank in 6 hours?
.
Rate of pipe A: 360 gallons per 3 hours
Rate of pipe B: 360 gallons per 4 hours
.
Gallons in 6 hours:
6(360/3 + 360/4)
6(120 + 90)
6(220)
13320 gallons
.
This appears to be a trick question.
Since the tank only holds 360 gallons, if both pipe A and B were turned on for 6 hours, 13320 gallons would come from the pipe, 960 gallons would overflow the tank and only 360 gallons would remain in the tank.
