Correct Answer - Option 1 : 175
Given:
Diameter of tyre is 0.5 m
Distance travelled = 275m
Formula used:
Distance travelled = no. of revolutions × circumference
Circumference = 2πr = πd
Calculation:
Let no. of revolutions be x
⇒ 275 = x × π × 0.5 = 0.5 × 22/7 × x
⇒ x = 175
∴ No. of revolutions will be 175
