That is 12 circumferences in 3 minutes.
That is 12 circumferences in 3%2A60=180 seconds.

1 circumference is 2%2Api%2A40 feet.
12 circumferences is 12%2A2%2Api%2A40 feet.

The people in the ride are moving at %2812%2A2%2Api%2A40%29%2F%283%2A60%29 feet per second. That is mostly in factored form and can be simplified.
