Average Speed = Total Distance / Total Time

Units:

* Speed: meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), etc.

* Distance: meters (m), kilometers (km), miles (mi), etc.

* Time: seconds (s), minutes (min), hours (h), etc.

Example:

If you travel 100 kilometers in 2 hours, your average speed would be:

Average Speed = 100 km / 2 h = 50 km/h
