A circular wheel 28 inches in diameter rotates the same number of inches per second as a circular wheel 35 inches in diameter. If the smaller wheel makes x revolutions per second, how many revolutions per minute does the larger wheelmakes in terms of x ?  Select
A) 48pi/x	B) 75x	C) 46x	D) 24x	E) 48x
C = (pi)d   C(small): (pi)*28   C(large): (pi)*35   Lets say the time horizon is 60 seconds, so during that time the smaller wheel covers a distance of (pi)*28*60 = (pi)*(1680) inches   (pi)*(1680) = (pi)*(35)(x)   pi*(48) = pi*(x)   48=x   Answer: E. 48x
