Giant Wheel Physics help

Hey everyone. I need some help with some information about the Giant Wheel for my trig class at school. What I really need is its revolutions per minute, the number of times it goes around completely in a minute. I looked at cp.com and they gave the height at 150 feet, and the rides section of pointbuzz gave it a diameter of 128 feet. But I really need its rpms. I'm sure its common knowledge for you guys so can somebody please help me out.
Thanks!

Don't know for sure, though I'd estimate 3-5, at best. Someone else probably has the right number.

It's approximently 3 RPM at the fastest speed in automatic mode.

It's 145 feet tall... as for RPM's.... that's not something that's 'general knowledge.' It depends on whether it's running a cycle, or just loading and going from color to color.

I'm feeling lazy, so I haven't dragged out the video. But I think it's around 3 RPM. For a Physics project, that's probably close enough. :)

Remember: C = pi * d where d=48m
Remember: 60V = C * o where o = angular velocity in RPM
Remember: Fc = V^2/r where r=d/2

Thanks, I'll use three. Even if it is wrong, my teacher will never know.
