# Fuel consumption and speed

I was wondering about the amount of fuel used for a given journey.
My model is that the same journey is made at two different constant speeds
I have assumed that instantaneous fuel consumption is proportional to the power produced by the engine at that point.
I an ignoring rolling resistance losses, and considering air drag only.
I have used power * time as a base for total amount of fuel used for each journey
