Question

3. Define speed. State its unit.


ANSWER



Distance travelled by a body in unit time.

units of speed :-
since the standard unit of length is metre and that of time is second, the standard unit of speed is m/s.
​

Answer 1

Speed can be thought of as the rate at which an object covers distance. ... Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour.
