SUMMARY
The displacement of a runner completing 6.5 laps around a 400m track is 160m, not 200m as initially thought. Displacement is defined as the shortest distance from the starting point to the endpoint, which in this case is influenced by the track's curvature. The misunderstanding arose from not considering the track's shape and the runner's starting position. A diagram accompanying the question clarified the correct displacement measurement.
