Sarah walks part way around a swimming pool She walks 50 yards north then 20 yards east and 50 yards south. The magnitude of her total displacement during the walk is 20 yards.
The total distance traveled (corresponding to the amount of gas the car would burn on such a trip) is 26 meters.The magnitude of the displacement vector = (Dfinal - Dinitial) = 4 meters north.
