A 400 gallon cylindrical tank is filled with water. A valve is opened at the bottom of the tank. A five- gallon jug fills in 21.5 seconds. Flow rate measurements are taken for 2 minutes, and are recorded as follows.
t(seconds)=30 60 90 120
q(gallons/minute)=13.88 13.64 13.41 13.17
Use this data to:
1) determine how much water will remain in the tank after 60 minutes of draining.
2) determine the time it will take to empty half of the water from the tank.
