A circular rim 28 inches in diameter rotates the same number of inches per seconds as a circular rim 35 inches in diameter. If the smaller rim makes x revolutions per second, how many revolutions per minutes does the larger rim make in terms of x?
$$A.\ 48\pi x$$
$$B.\ 75x$$
$$C.\ 48x$$
$$D.\ 24x$$
$$E.\ \frac{x}{75}$$
The OA is C.
I don't have clear this PS question.
I know that the 2 rims have the same revolutions per seconds but I don't know how can I represent it to solve it. I appreciate if any expert explain it for me. Thank you so much.
