length AB=200m=2R
time taken to complete one round=40 sec
let the starting point be A
in 140 sec or 2 min 20 sec number of rounds completed=14040=3.514040=3.5
distance traveled=3.5 * (2*ππ*R)=3.5*2*ππ*100 m=2200 m (approx)
displacement refers to change in position from the starting point.the final point is B
as after 3.5 revolutions(starting from A) the athlete will be at B.
displacement=200m
