A jogger starts at the origin of a straight track that extends east–west. During her workout she follows this sequence without stopping:
(a) Find the jogger’s net displacement when the workout ends. Include the sign that indicates direction.
(b) Calculate the total distance covered during the workout.
(c) Compute the ratio of the distance found in part (b) to the magnitude of the displacement found in part (a). Interpret what this ratio indicates about the jogger’s path compared with a single-direction run of the same final displacement.
