Question
If a wheel covers a distance of 880 m in 40 rotations,
then the diameter of the wheel is?Solution
Distance covered in 40 rotations = 880 m Distance covered in 1 rotations = 880/40 = 22 m ∴ Distance covered in 1 rotation = circumference of the wheel 2πr = 22m 2r (diameter) = (22 × 7)/22 = 7 m
