Use Direct and Inverse Variation · Exercise 27
Write an inverse variation equation to solve the following problems.
The time required to empty a tank varies inversely as the rate of pumping. It took Janet 5 hours to pump her flooded basement using a pump that was rated at 200 gpm (gallons per minute),
ⓐ Write the equation that relates the number of hours to the pump rate.
ⓑ How long would it take Janet to pump her basement if she used a pump rated at 400 gpm?
