A Ferris wheel travels around at a rate of 25 m/min and takes 19 min to do a full revolution. What is the radius of the Ferris wheel?

After 19 min of spinning, the Ferris wheel completes one revolution, so any fixed point on the wheel returns to the position at which it started. This point would cover a distance equal to the circumference of the wheel, equal to 2π times the radius r of the wheel.

This means the circumference of the wheel is

(25 m/min) * (19 min) = 475 m

and so the radius of the wheel is

(475 m) / (2π) = r = 75.59 m

which most closely matches D.
