A Ferris wheel that has a diamter of 40 feet makes one revolution every two minutes. What is the speed of the seat on the rim of the wheel (miles per hour)? If you are the last person to get ont he Ferris whell, what will the coordinates of your location be after 3 minutes? (Assume taht at t=0 you are at the lowest point on the ride.)
Thank you JSAM for everything

The distance travelled in two minutes would be the circumference of the wheel. This is pi x D
22/7 x 40 = 880/7 = 126 to the nearest foot
This is 42 yards so as there are 1760 yards in a mile it would take 1760/42 x 2 to get the number of minutes to travel 1 mile.
This equals 84 minutes to nearest minute so the speed would be
1 x 60/84 mph = 0.714 mph.
As the wheel completes a full rotation in two minutes then after three minutes you would have completed 1 1/2 rotations so your position would be diametrically opposite to your starting point, ie right at the top of the wheel.

0.0118999722 mph
you will be on the top after 3 min
