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 50 revolutions. How many revolutions does the second wheel make in covering d feet?	Choose the correct answer:
A) 50xy  B) 50y - x  C) 50x - y  D) 50y/x  E) 50x/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)   50 = d/(x*pi)   d = 50 * x * pi ---------- (3)   From equation (2)   Revolutions = d/(y*pi) = (50 * x * pi) / (y*pi) = 50x/y   Answer (50x/y)
