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.
Yes, you’re technically right, that’s at least what I was trying to say. “Linear” and “everything is in a multiplicative relation” are really close in my head, though, so I made a mistake.
