Dora runs one lap around the track, finishing where she started. Clark runs a 100-yard dash along the straight side of the track.Which runner had a greater change in position, start to finish?

Answer 1

Since Dora runs one lap around the track and finishes where she started, her change in position is zero. On the other hand, Clark runs a 100-yard dash in a straight line, so his change in position is greater than zero. Therefore, Clark had a greater change in position, start to finish.
