A large container holds 5 gallons of water. It begins leaking at a constant rate. After 10 minutes, the container has 3 gallons of water left. At what rate is the water leaking? After how many minutes will the container be empty?
5 - 10 x = 3 10 x = 5 - 3 10 x = 2 x = 10 : 5 x = 0.2 The rate is : 0.2 gallons / minute 5 - t * 0.2 = 0 t * 0.2 = 5 t = 5 : 0.2 t = 25 min Answer: After 25 minutes the container will be empty.
