What is the most efficient speed to drive? Assume that a modern car has a 2 m2 frontal area and a drag coefficient of 0.25. Assume that there are two sources of energy dissipated during driving: a constant 250 W required to operate the car and the energy dissipated to aerodynamic drag. In terms of energy required to travel a given distance, what is the most efficient speed to drive?
