A circular rim 28 inches in diameter rotates the same number of inches per second as a circular rim 35 inches in diameter. If the smaller rim makes x revolutions per second, how many revolutions per minute does the larger rim make in terms of x?

The number of inches of both are equal
After one second the smaller rim has rotated the number of inches is 2pi*28*x
So in 1 minute the bigger one has the number of revolution is
2*pi*28*x*60/(2*pi*35)=48x
