a circular wheel radius is 1.75m.for covering 11k.m how much time it revolve? Choose the correct option:
A) 10
B) 100
C) 1000
D) 10000
E) 50

Rationale: distance traveled in 1 round = perimeter = { 2 * 22 / 7 * 175 / 100 } m = 11 m total no . of revolution in covering 11 km = 11000 / 11 = 1000 answer c
Answer: C
