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 hA.
