ANSWER:-
An athlete completes one round of circular path of diameter 200m in 40sec
radius=diameter/2
=200m/2
=100m
No. of rounds he can make in 2mins 20sec,
t=2×60sec+20sec
t=120+20
t=140sec
No. of rounds=140sec/40sec
=7/2
=3.5 rounds
it means he covered 3 complete rounds and half of the distance.
Distance covered by the athlete,
=3.5×2π r
=3.5×2×22/7×100m
=0.5×2×100×22
=1×100×22
S=2200m
therefore distance is 2200m and displacement is 200m
