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 1000 revolutions. How many revolutions does the second wheel make in covering d feet?  Pick.
A) 1000xy
B) 1000x/y
C) 1000x - y
D) 1000y/x
E) 1000y - x
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)   1000 = d/(x*pi)   d = 1000 * x * pi ---------- (3)   From equation (2)   Revolutions = d/(y*pi) = (1000 * x * pi) / (y*pi) = 1000x/y   Answer (1000x/y)
