Speed is the rate of change of any motion with respect to time.

Speed is basically an apparture to Count or calculate how fast an object's motion is

Example:-

A moving train has its own speed and its significanance can be calculated by a fixed point of reference .etc

Answer 2

Hey mate,

Here is ur answer.....

Speed,distance and time are inter-related and therefore to find anyone of them, it is necessary that we are provided with the latter two.

The expression is——

Distance= speed*time

It can also be expressed as

Speed= distance/time

For example-

If the distance travelled by a car is 3 km and it takes 5 minutes to travel this distance then

Speed = 3000m / 5*60

3000/300

=> 30m/sec

NOTE: here 3 km and 5 mins are converted into metre and second as they are the standard unit of distance and time.

STANDARD UNIT OF SPEED IS  m/s

Hope this helps you ♥️♥️
