help help help! A car travels at a speed of 64 mph and its fuel consumption is 28 mpg. It has an 11-gallon tank, which was full when it started but at that very moment began to leak fuel. After 112 miles the car stops with a completely empty tank. How many gallons per hour was it losing?

Question

4 gallons per hour.

Remember that Time = Distance ÷ Speed.

The car travels 112 miles, which uses 112 miles ÷ 28 mpg = 4 gallons of fuel. This leaves 7 gallons.

The car took 112 miles ÷ 64 mph = 1.75 hours (1 hour 45 mins) to travel the 112 miles, which means the 7 gallons were lost in 1 hour 45 mins.

Therefore the car was losing the fuel at a rate of 7 gallons ÷ 1.75 hours = 4 gallons per hour. QED.
