You are standing near a set of train tracks and hear the whistle of a coming train. You look to your left and notice the train traveling from left to right at 150 miles per hour. Yea i know Bolt is standing at the end of the passenger car on the train and begins to run. To you standing still it appears that Usain Bolt is running at a speed of 177 miles per hour. How fast is Usain Bolt actually running relative to the train?
