1. A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equation: V(t) = 65t + 280, where t is the time, in minutes, the pump has been on. At what rate, in gallons per minute, is the water being pumped into the tank?

• 65 minutes per gallon

• 65 gallons per minute

• 280 gallons per minute

• 280 minutes per gallon

A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equation: V(t) = 65t + 280, where t is the time, in minutes, the pump has been on. The pumps will turn off when the volume in the tank hits 10,000 gallons. To the nearest minute, after how long does this happen?

• 154 minutes

• 650,280 minutes

• 150 minutes

• 159 minutes
