A fire engine travels six miles to an out of control bonfire. It travels at a speed of 32 mph. The fire engine's tank holds 500 gallons of water but has been leaking throughout the journey at a rate of 20 gallons per hour.

If the fire engine needs 496 gallons of water to put out the fire, will it have enough, and if so, how much water will it have to spare?

Show Answer

One quarter of a gallon.
