It is not linear but some sort of hyberpolic function as the OP is describing: double the speed and you halve the travel time, you move closer to zero travel time but never reach it. With a linear relation you would reach zero travel time at a specific speed point.

Travel time is just distance/speed. I suppose that's only linear in distance in the technical sense, being inversely proportional to speed, but the point that there's no dark magic or non-elementary school math involved stands.

And that makes the function like ’y = 1/x’ which is not a linear function. No dark magic, just math. The gist is the proportial part, not just inversely.
