SPEED / VELOCITY:
Starting with the basic of the basics we talk about the speed that how it relates with the time As we talk in Physics about the speed we can refer speed to as "velocity" ,both are same equal terms that can be pronounced.
So most of us don't know about what the speed is actually?
We often use these terms my car ran at the speed of 80 km/h.
Or he ran in the race 5 m/s.
So what are these?? km/h or m/s.
Well basically these are the units of speed but they can define the speed or the velocity exactly.
You can easily see that kilometres per hour define that how many kilometres will the body travel in a particular or a specified time.
for instance we say 50 kilometres per hour. It means if a constant speed of 50 is maintained by the car, the car will travel 50 kilometres exactly in 1 hour and then changing the time from 1 hour to 2. 100 kilometres will be travelled by the car in 2 hours.
In terms of meters per second. He ran 5 meters per second. This is if he runs at the speed of 5 he will cover the distance of 5 meters in just one second.

Hope this is clear to you all :)
