I hope someone can help, Thank You!

The wheels of a machine are identical. They have an outer circumference of 10 cm and an inner circumference of 5 cm. If the crank is rotated one quarter turn clockwise, where will the clock's hand point?

More information needed. (Until the last phrase, I didn't even know that you were talking about a clock.) If we don't know where the hands were pointing originally, how can we know where they will point after a quarter turn?
