In walking a kilometer, you use about 100 kJ of energy. This energy comes from the oxidation of foods, which is about 30% efficient. How much energy do you save by walking 7.02 kilometers instead of driving a car that gets 10.8 km L1 of gasoline (25.4 miles per gallon)? Take the density of gasoline to be 0.680 g mL-¹ and its enthalpy of combustion to be -48.0 kJ g¹. kJ
