Why the unit of speed is derived unit?

Answer 1

Derived SI Units

In physics there are many quantities that cannot be expressed by a single base unit. 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.
