A wheel has a diameter of x inches and a second wheel has a diameter of y inches. The first wheel covers a distance of d feet in 300 revolutions. How many revolutions does the second wheel make in covering d feet?	Choose the most appropriate option.
A) 300xy B) 300x/y C) 300x - y D) 200y/x E) 600x/y
First Wheel with diameter x inches ----&gt; So the circumference = x*pi --------- (1)   Second Wheel with diameter y inches ----&gt; So the circumference = y*pi --------- (2)   Revolutions = distance/circumference   So, from equation (1)   300 = d/(x*pi)   d = 300 * x * pi ---------- (3)   From equation (2)   Revolutions = d/(y*pi) = (300 * x * pi) / (y*pi) = 300x/y   Answer (300x/y)
