When calculating an average velocity in a problem containing multiple velocities each occuring for different lengths of time, would I be correct in calculating the total displacement and then dividing by the total time? For example: Suzy goes for a jog one day. She runs at an average velocity 3 m/s north for 2 minutes and then an average velocity of 5m/s south for 3 minutes. What is her average velocity? I believe it would be solved like this: d=vt = (3m/s)(120s) =360m d=vt = (-5m/s)(180s)=-900m total d = 360m + (-900m) =-540m total t =300s Average V = -540m/300s = -1.8m/s Thank you.
