On routes with few starts and stops, the route with the lower speed limit is the more fuel efficient one. Higher speed means higher drag (by the square of speed).
Mostly because that would be a shorter route then, cars have gears and are more efficient under a higher load so a higher speed, usually around 100kph is most efficient
Drag is where energy is lost. Drag is a function of speed.
I know, but a car's efficiency is dependent on more factors than speed and friction alone
