answer
= 11:1
explanation
= let the diameter of the circle = x
time taken to complete one revolution = 40 seconds
total time taken by the particle = 140 seconds
it means that particle cover 140/40 rounds in 140 seconds
140/40 = 3.5 rounds
distance covered = 2 x 22/7 x X/ 2 X 3.5 = 22/7 X x 3.5 = 11 x
displacement = diameter of the circle = x
ratio of distance and displacement
=11x:x
=11:1
