Question
If a wheel covers a distance of 1760 m in 80 rotations,
then the diameter of the wheel is?Solution
Distance covered in 80 rotations = 1760 m Distance covered in 1 rotations = 1760/80 = 22 m Distance covered in 1 rotation = circumference of the wheel 2 x 22/7 r = 22m r = 7/2 2r (diameter) = (22 x 7)/22 = 7 m
