If cyclist is covering a circular distance of diameter 15 inches at the speed of x inches/min, and another cyclist is covering a circular distance of diameter 25 inches at the speed of y inches/min then what is the value of y in terms of x if both the cyclists cover the distance at the same time?  Pick one.
A) 2x/4	B) 6x/2	C) 7x/3	D) 5x/3	E) 4x/3
t=S1/V1=S2/V2   or 15/x=25/y   or y=25x/15=5x/3   Answer is 5x/3
