Does it tell you the distance between dallas and Chicago?

seems like there should be more to this problem...

anonymous · Answer

otherwise its as simple as taking the average velocity which is the same as taking any average. Do you recall the way to take an average of a group of #'s?

No, it doesn't, but I would assume it is 2d because it goes from Dallas to Chicago and then back.
