When one gallon of gasoline is burned in a car engine, 1.22 x 108 J of internal energy is released. Suppose that 1.05 x 108 J of this energy flows directly into the surroundings (engine block and exhaust system) in the form of heat. If 5.0 x 105 J of work is required to make the car go one mile, how many miles can the car travel on one gallon of gas?
