Answer:

time taken to complete one round: 4 sec

Total time: (2×60+20) sec

=140 sec

no. of rounds completed: 140/40

=3.5

distance covered: 2πr×3.5

=2×22/7×200/2×3.5

=2200m

if the athletes starts from the point A on completion of 3.5 rounds, then he/she will

be at point B.

thus,

displacement: AB=200m
