Derek runs 4 laps around the track. if each lap around the track is 0.25 miles long, and he starts and stops in the same location, what is derek's displacement?

Derek's displacement is 0 miles, because he starts and stops in the same place. The distance he covered would be 1 mile.

Distance is the total length covered.
Displacement is the distance between the starting point and the end point. If Derek started and stopped in the same place, he had a displacement of 0.

Hope this helps!
