first consider the force of propulsion.Each gallon of gasoline contains an amount of energy,say K,if C(r) represents the amount of fuel burned per unit time,then C(r)*K represents the power available to the car.Assuming a constant rate of power conversion,it follows that the converted power is proportional to C(r)K,because power is the product of force and velocity for a constant force,this argument yields the proportionality relation
