Speed = Distance / Time

Unit: The unit for speed is typically meters per second (m/s) or kilometers per hour (km/h).

Here's a breakdown of the units:

* Distance: Can be measured in meters (m), kilometers (km), miles (mi), etc.

* Time: Can be measured in seconds (s), minutes (min), hours (h), etc.

Example: If you travel 100 meters in 20 seconds, your speed is:

Speed = 100 meters / 20 seconds = 5 meters per second (m/s)
