Can't you set up the equation?In 1893, George Ferris engineered the Ferris Wheel. It was 250 feet in diameter.
If the wheel makes 1 revolution every 40 seconds, then: .

is a person on the Ferris Wheel exactly 125 feet above the ground?
The question is: When is ?
We have: .
The rider is above 125 feet on the interval:(B) During the first 40 seconds of the ride, over what interval of time
