Larry leaves home at 9:03 and runs at constant speed to the lamppost(200 yards from the start). He reaches the lamppost at 9:07, immediately turns, and runs to the tree(1200 yards from the start). Larry arrives at the tree at 9:13.

What is Larry’s average velocity, in yards/min, during each of these two intervals.

I got 50.0 y/m and 167 y/m

1. I can say noting about velocity because all I have is speed. For velocity direction is also required.
For speed you can use a speedometer.
For velocity you need both a speedometer and a compass.
