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
The slope of the line is the rate of change of y with respect to x. Since the units are already gallons and minutes, the rate that the water is being pumped is 65 gallons per minute. Hope this helps! :)
