Let the diameter of the circle = x
Time taken to complete 1 revolution=40 seconds
Total time taken by the particle = 140 seconds.
It means that particle covers 140/40 rounds in 140 seconds
140/40 = 3.5 rounds
Distance covered = 2×22/7×x/2×3.5
= 22/7x × 3.5
= 11x
Displacement = diameter of the circle= x
Ratio of distance and displacement
= 11x : x
= 11 : 1
