Question

Write the definition and S.I. units of speed ?​

Answer 1

Answer:

Speed is defined as the distance travelled by a body per unit time. Its unit in SI is km/s.

Answer 2

Speed is defined as the rate at which someone/something is moving and its S.I. unit is metre per second or metre/second.

In everyday life, the speed of any object can be defined as the magnitude of the rate of change of its position with respect to time.

Hence, the S.I. unit of speed can be considered as the combination of basic units of distance and of time.
