**bobpursley**, Sunday, February 7, 2010 at 7:44amLet A to B be 100 miles, and B to A be 100 miles.

Distance=200 miles

So what is the time

timeAB=100/4.5 timeBA=100/3

add the times to get total time

average velocity=distance/totaltime

Velocity=displacement/time

= (finalposition-initialposition)/time
