Answer:
Distance and displacement are two terms that appear to be identical but have quite different meanings and definitions. The term “distance” relates to how much ground an object has covered during its motion, whereas “displacement” refers to how far out of place is an objectThe diameter of the circular track = 200 m
Radius (r) = 200/2
r = 100 m
Time is taken by an athlete to complete one round = 40 seconds.
Displacement = ??
Speed = Distance/Time
Total time athlete moves – 2 min 20 seconds
2 min 20 seconds = 2 × 60 + 20
2 min 20 seconds = 140 seconds
