Not true. Drag is proportional to the square of velocity so a
constant speed route can take less energy than one that involves a
variable speed. Even if the constant speed route is longer. My reply
is irrelevant though because your problem is badly specified.

I am sorry, I meant to include if traveling at the same speed.
same speed longer path = more fuel than same speed shorter path.
