ˉv=dt where d is the overall displacement, t is the time it takes to complete the displacement, and v is the average velocity of the item. As a result, the average velocity is typically zero when the overall displacement is zero.

The change in position divided by the distance traveled is how average velocity is calculated. For instance, someone traveling at an average speed of 40 miles divided by 40 minutes, or 1 mile per minute, is traveling 20 miles north and then 20 miles south (60 mph). However, average velocity takes into account total displacement rather than just distance.

Average Speed = TT/TD (20/50 = 2.5 m/sec) (b) Average Speed = TT / TD = 22 / 50 = 2.2727 m/sec (c) Average Speed = TT / TD = 20 + 22 / 50 + 50 = 2.38 m/sec
