Question
If a wheel covers a distance of 660 m in 30 rotations,
then the diameter of the wheel is?Solution
Distance covered in 30 rotations = 660 m Distance covered in 1 rotations = 660/30 = 22 m ∴ Distance covered in 1 rotation = circumference of the wheel 2πr = 22m 2r (diameter) = (22 × 7)/22 = 7 m
