A runner travels around a rectangle track with length = 50 meters and width = 20 meters. After traveling around the rectangle track two times, run back to the starting point. Determine distance and displacement.

Explanation

Circumference of rectangle = 2(50 meters) + 2(20 meters) = 100 meters + 40 meters = 140 meters.
Travels around the rectangle 2 times = 2(140 m) = 280 m.
Distance = 280 m.
Displacement = 0 m. (The runner returns to the starting point).
