If a motor bike's wheel is 12 cm diameter and rotating at the rate of x cm/min and another motor bike's wheel is 6 cm diameter rotating at the rate of y cm/min and if both the bikes reach the distance at same time then what is the value of y in terms of x?
Choose the correct answer:
A) 4x/2  B) 3x/6  C) 4x/2  D) 1x/2  E) 2x/3
t=S1/V1=S2/V2   or 12/x=6/y   or y=6x/12=1x/2   Answer is 1x/2
