A runner dashes from the starting line (x = 0) to a point 80 m away and then turns around and runs to a point 39 m away from the starting point in 23 seconds.What is the runner's average velocity in the previous problem?

Answer 1

Change in location (41 m) divided by time. Is 23 seconds the total time spent running or the time spent running back? You don't make that clear.

Answer 2

6.4
