In school we learned ” what you save in energy, you have to increase the way.” By that rule you should use the exact same amount of energy (fuel) for the same distance no matter what speed. I’ve asked a few people, but no-one could give me a good answer.

The harder you accelerate, the worse your fuel consumption is. The faster you drive, the harder the wind resistance holding you back is. Every bit of braking you do is wasting energy you used accelerating in the first place.
So, accelerate slowly, maintain low speed, coast early instead of brake. You see truckers do this all the time, they slog up a hill very slowly, coast half a mile to get the green light rather than stop and start up again, and draft behind other trucks so they fight the wind resistance instead.
