Answer:
b. 0 and 800m respectively
Explanation:
the word "elliptical" means oval or egg-shaped. this means that the displacement of the athlete is 0 since they were running in a circle and stopped where they started, so their end position is not different from their original position.
the distance covered by them is 400m × 2 = 800m.
