Question: A typical compact car experiences a total drag force at 55 mi/h of about 400N. If this car gets 37milespergallon of gasoline at this speed, and a liter of gasoline (1 gal = 3.8 L) releases about 3.2x10⁷J when burned, what is the car's efficiency?

Please use as much detail as possible in your answer. Thanks.
