If the unicorn seat on a merrygoround is 5 feet from the center, and the merrygoround completes a full rotation in 6 seconds, how many feet does the unicorn travel in one second?

2pi*5 ft / 6s = 5pi/3 ft/s
When did you ever see a carousel make a complete turn in 6 seconds?!?!? Talk about dizzying!
