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..
