Using Supernovas in 1998 they found out galaxies are farther from us than we thought. This didn't correspond well to closed universe or open universe but to an accelerated expansion.

My question is, we know how fast we are drifting apart, but why would a farther distance mean we are expansion is accelerating? It seems contradictory to me.
For example we know someone is traveling 100 mph we would assume he traveled 100 miles since the last hour, but if he traveled 110 miles we would assume he decelerated to 100 mph.
Can someone explain why I'm retarded?
