Tangential Speed of Passenger on 10m Radius Ferris Wheel

Homework Statement

I thought this would be an easy question for me, but I can't figure it out.
"What is the tangential speed of a passenger on a Ferris wheel that has a radius of 10 meters and rotates once every 30 seconds?"

Homework Equations

Tangential speed = rotational speed x radial distance

The Attempt at a Solution

Tangential speed = 2RMP x 10 meters
= 20...what units? Not m/sec, not RPM...
...But...
I figured the circumference is 62.83 meters x 2RPM = 125 meters per minute

With the information that it's 2RPM, you can very easily find the angluar velocity, ω. I'd use that as a starting point to finding the tangential velocity.

That doesn't help...
thanks though
