Arunner goes around a 1 mile track if they end up at their starting position what is their distance traveled

1 mile

Explanation:

The distance travelled is the length of the path that the runner traveled.

As you have stated he has traveled a 1 mile track so the length he traveled is 1 mile.

The point of ending matters only in displacement not in distance. In displacement we measure the unidirectional shortest distance between two points where the displacement in this case is 0.
