Question

Define speed. what is the SI unit of speed?​

Answer 1

$Your \: answer \: is \: here :$

⇒Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.

⇒So the SI unit of speed is metre per second (m/s). Speed is also measured in kilometre per hour (km/h). The average speed of a moving object is defined as the total distance covered by it divided by the total time taken.
