When it is burned, 1 gallon of gasoline produces 1.30×10^8 J of energy. A 1500 kg car accelerates from rest to 36.0 m m/s in 10.0 s. The engine of this car is only 15.0 % (which is typical), meaning that only 15.0 % of the combustion energy goes into accelerating the car. The rest goes into things like heating up the engine and exhaust gas.

Part a: How many gallons of gasoline does the car use during its acceleration?

Part b: How many such accelerations will it take to burn 1 gallon of gasoline?

Where do I start??
