This is about driving in a city: you spend most of your time accelerating, decelerating, and waiting at intersections. 30 vs 50 km/h doesn't make much of a difference - travel time does not scale linearly with it.

Whether you can hold the maximum as the average doesn't mean there is no proportionality. If you're traveling at 50 km/h and then have to come to a stop and accelerate again your average speed might be 25, but if the maximum speed is 30 then your average speed might be 15.
