Answer:
Sally's displacement is 10 m less than her distance traveled.
Explanation:
It is given that, Sally walks 10 meters forward and then 5 meters backwards. The total path covered by a particle is called total distance covered by it and the shortest path covered by it is called its displacement.
From the attached figure, A is the initial position of Sally. Initially, he moves from A to B. It covers a distance of 10 m then he moves from B to C. So, the total distance covered by Sally is AB+BC = 15 m
While her displacement is AC i.e. 5 m
So, the correct option is (b) i.e. her displacement is 10 m less than her distance travelled.
