Average velocity = total distance / total time
Example:
I travel from Rotterdam to Amsterdam (100 km) with an average speed of 80 km/h and return with an average speed of 120 km/h.
Then my average verlocity is NOT 100 km/h, but:
Time for the trip out:
Time for the trip back:
Total time:
Average velocity:
This may be counter-intuitive, but remember you spend more time in the slow mode than in the fast mode.
