Question

a boy moves along the boundary of a square field of side 10 m in 40 seconds what will be the distance and displacement of the boy at the end 160 seconds from his initial position​

Answer 1

Answer:

distance = 160m

displacement = 10m

Explanation:

-in 160 seconds the boy would have completed 4 rounds.

-one round is the perimeter of the square which is 40m.

- so 4 rounds means 4*40=160m

- displacement is 10m as that is the distance it moves along a straight path
