Speed = Distance / Time

* Speed is the rate at which an object moves.

* Distance is the total length of the path traveled.

* Time is the duration of the journey.

Units:

* Speed is typically measured in units like meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).

* Distance is measured in units like meters (m), kilometers (km), or miles (mi).

* Time is measured in units like seconds (s), minutes (min), or hours (h).

Example:

If a car travels 100 kilometers in 2 hours, its speed is:

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