Question 1210361: The London Eye Ferris Wheel in England is 500 ft. tall and takes 30 min. to make one revolution. Determine speed.
Check my calculations, please.
500 ft. = diameter.
Circumference = pi * diameter.
3.1416 * 500 = 1570.8 - 1571 ft.
Distance / Time = Rate.
1571 / 5280 = .2975 mi.
.2975 / .5 hrs. = .595 mph.

Due to my curiosity, I asked Google "what is The London Eye Ferris wheel diameter ?"
It answered "The London Eye Ferris wheel is of 394 feet (120 meters),
according to Britannica. It stands 443 feet (135 meters) tall".
So, the right description is different from the given in the post.
It is useful to know that
(1) Math problem descriptions sometime are inadequate to real life;
(2) Math problem descriptions extracted from the Internet are often inadequate to real life;
(3) Math problem descriptions extracted from the Internet sometime are absolutely inadequate to real life.
When you see such inadequacy, it is a clear sign that the problem was created by an unprofessional Math composer.
