displacement
displacement=final position - initial position.
after his completion of 1 round he will arrive at the same place so his final and initial is same.
therefore,his displacement will be 0
distance
distance will be the circumference of the circle.
Circumference=2πr
=2×22/7×2020m
=44/7×2020
= 12,697.14m
