Answer

The magnitude of the displacement vector is 100 m and the displacement vector points to the west.

Work Step by Step

If the runner runs 2.5 times around the track, the runner will end up at the point (-50 m, 0). The distance from the starting point is 100 meters and the direction is to the west. Thus, the magnitude of the displacement vector is 100 m and the displacement vector points to the west.
