Imagine that your are traveling in a circle that has a 4 mile circumference at a constant speed of 30 mph. How long does it take you to make one complete revolution around the circle? What is your average speed for the trip? What is your average velocity for the trip? Why are they not the same?

What are your thoughts on the question, mickey-one? How would you go about solving it? What is the first step?

Two type of velocity
1. linear 2. angular
When you talking about second one than you should not count it mile/second. But you should count it in rpm, degree/min, radian/ second
If your circumfarance is 4 mile than dia of circle is 1.273077 mile so for completing one revolution you need 8 min at average speed of 30 mile/ hour.
