Question

A jet's average speed is 520 mi/h when flying from Dallas to Chicago and 580 mi/h on the return trip. What is the jet's average speed for the entire trip?

Answer 1

Does it tell you the distance between dallas and Chicago?

Answer 2

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

Answer 3

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?

Answer 4

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

Answer 5

@memman Never mind I figured it out by myself.

Answer 6

Thanks though
