Explanation:
Therefore, the unit of speed is the meter per second, or m/s. The unit meter per second is called a derived unit, meaning that it is derived from the seven SI base units. Units can be combined together in many possible combinations, and any physically-significant quantity will have its own units

On SI (International System [of Unit]), the unit of speed is **meter per second**, so the unit is derived from the unit **meter** and from unit **second**.
Other systems of unit could have different basic units, so speed could or could not be a derived unit.
Note: speed (of light) is used to derive the length of meter, but meter is still one of the 7 fundamental units (of SI).
