Slope Intercept Rate of Change

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
