I think you are thinking about a case where someone goes 120km/h for 1 hour and then 80km/h for 1 hour instead of going over a fixed distance at 120km/h and then going over the same distance at 80km/h.

No. As I stated, the distance is the same.

I was responding to the person mentioning 100km/h as the correct answer (firstlink).
