If the radius of a wheel is 42 cm and it makes 20 rotations in 1 h, then find the time taken by the wheel to cover a distance of 528 m.
The following steps are involved in solving the above problem. Arrange them in sequential order.
(A) Time taken to complete 200 rotations `=200xx(1)/(2)=10h`
(B) The number of rotations required to cover a distance of 528m
`=("Distance")/("Circumference")=(528m)/(264cm)=(52800)/(264)=200`
(C) The distance covered by the wheel in `"1 rotation"="Circumference of the wheel"=`
`2pir=2xx(22)/(7)xx42=264cm`
(D) Time taken to make 20 rotations = 1 h
