Solution

The correct option is B

35m, 5m


Distance = speed × time
=1040×140
=35m

Find the distance betw the en initial and final position to find out displacement.
While travelling 35m around of a square of perimeter 40m, the body is 5m off its initial position.
So, its displacement will be 5m.
