Explanation:
Diameter of a circular track = 200 m
length of the track = 3.141*200= 628.3 m
time taken to complete one round = 40sec
speed of the athlete = 628.3m/40s
= 15.71m/s
total time of running = 2min 20s = 2*60+20= 140s
total distance covered in 140s = 15.71m/s *140s= 2199.4 m
number of rounds = 2199.4m/628.3m = 3.5
the athlete will be opposite to the starting point.
displacement =diameter of the track=200 m
distance travelled =2199.4=2200 m
