A wheel has a diameter of y inches and a second wheel has a diameter of x inches. The first wheel covers a distance of d feet in 100 revolutions. How many revolutions does the second wheel make in covering d feet?
Choose the correct choice from the following
A) 100xy
B) 100y - x
C) 100x - y
D) 100y/x
E) 100x/y
First Wheel with diameter y inches ----&gt; So the circumference = y*pi --------- (1)   Second Wheel with diameter x inches ----&gt; So the circumference = x*pi --------- (2)   Revolutions = distance/circumference   So, from equation (1)   100 = d/(y*pi)   d = 100 * y * pi ---------- (3)   From equation (2)   Revolutions = d/(x*pi) = (100 * y * pi) / (x*pi) = 100y/x   Answer (100y/x)
