Answer 2

Answer:

Distance = 62.8m

Displacement = 0

Explanation:

The boy is moving in a circle of diameter 5m

So Radius = 5/2

Circumference of the circle = Distance covered in one revolution

2πr = 2 x 22/7 x 5/2

      = 15.7 m

Distance travelled in 4 Revolutions = 15.7 x 4

                                                           = 62.8m

Displacement is 0 because starting and ending position is same
