m/s
The definition of speed it the time taken to cover a distance.
The SI derived unit for speed is metres per second.
we know , speed =distance /time .
it means distance in m and time is taken in sec.and ratio is taken , which forms speed kin m /s.
SI unit of speed is m/sec. It describes distance traveled per unit time.
The SI has 7 base units: http://en.wikipedia.org/wiki/SI_base_unit Also, the SI has tens of derived units - perhaps hundreds of them, since you can combine the base units in many ways. Those units are ultimately derived from the 7 base units. For example, units for area, volume, speed, force, energy, pressure, electric charge, voltage, and many more, are derived from some of the base units. http://en.wikipedia.org/wiki/SI_derived_unit
Base units
Seven metric base units make up the foundation of SI. And Specific combinations of SI base units yield derived units. That's why the differ.
There are 7 base SI units and all other are defined using these 7 base units. See the related question below:[http://wiki.answers.com/Q/What_are_all_the_SI_unitsWhat are all SI units?]
Velocity is comprised of a speed part and a direction part. (any SI unit of length)/(any SI unit of time) is a unit of speed. The simplest one, in SI base units, would be meters/second . Direction is most often stated as an angle.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.

The International System of Units (SI) has two type of units, base units and derived units. Speed is a derived unit. Its unit is Meter/sec. Its a scalar quantity.
