Answer:

2 min + 40 sec = 2×60 + 40 = 160 sec...

diameter of circle = 200m

distance cover by athlete after complete one round = pi*200

displacement after complete one round = 0

because initial and final place is same not change...

160 sec is equal to 4*40 sec

no. of complete round after 160 sec = 160/40 = 4

so displacement = 0

hope it will help u..

pls mark me as brainliest..
