Question
A wheel has a diameter of 28 meters and rotates at a
speed of 25 revolutions per minute. How much distance will the wheel travel in 32 minutes?Solution
ATQ, Radius of the wheel = (28/2) = 14 metres So, circumference of the wheel = 2 × π × radius = 2 × (22/7) × 14 = 88 metres Distance covered by the wheel in one revolution = circumference of the wheel. So, distance covered by the wheel in one minute = 88 × 25 = 2200 metres (2200/1000)= 2.2 km So, distance covered by the wheel in 32 minutes = 2.2 × 32 = 70.4 km
