Distance covered is 31 * 2=62cm
Displacement is 0 because it depends on intial and final position.

Given, diameter = 15m
circumference = π × diameter
=(22/7)*15 meters
Hence distance covered will be
=2 * circumference
= 660/ 7 m
= nearly 94.3 meters
Displacement will be 0 because particle return to same position.
