A circular rim 50 inches in diameter rotates the same number of inches per second as a circular rim 15 inches in diameter. If the smaller rim makes x revolutions per second, how many revolutions per minute does the larger rim makes in terms of x ?	Choose the correct answer
A) 48pi/x B) 75x C) 48x D) 24x E) 200x
Revolutions - circumference of the rim.   =&gt; 50pi*X*60 = 15pi*Revolutions   =&gt; 10/3 *X *60 = Revolutions =&gt; 200X - Option 200x
