Starting at the same spot on a circular track that is 80 meters in diameter, Hillary and
Eugene run in opposite directions, at 300 meters per minute and 240 meters per minute,
respectively. They run for 50 minutes. What distance separates Hillary and Eugene when they finish? There is more than one way to interpret the word distance in this question.

Do they mean the chord and the arc?

They mean the chord - "distance" means "shortest distance".

My impression was that the sentence in red is a part of the problem statement and not the OP's words. In this case, it is probably an invitation to find the lengths of both the arc and the chord.
