Supposedly going faster uses more fuel. But your getting to the place quicker. Shouldn’t you just be using the same amount of fuel as if you were driving slower and getting there later?

Answer 1

Most commonly, the burning is expressed in [L/100km]. So driving at 60km/h will make you use up 2L of fuel after 100km. Driving at 140km/h will use up 8L after 100km. It doesn’t go up proportionately because of wind resistance and the suboptimal work of the engine.
