Answer 2

Distance covered by Brittney is: 400 M

Total distance of track:400

Since she came back to the same place, her displacement is= 400-400= 0

Explanation:

displacement is the direction from the starting point and the length of a straight line from the starting point to the ending point. If a runner was going to run 400 meters (one lap around the track), they would start and stop at the same place on the track. Therefore, their displacement would be 0.
