Starting from a pillar, you run a distance 200 east (the x-direction) at an average speed of 5.0 , and then run a distance 280 west at an average speed of 4.0 to a post. What is the average velocity?? :confused:

I already answered this in your other post. Velocity= displacement/time

200-280/110=0.7272 to the west
