Explanation:
Velocity is a vector quantity, meaning it has size and direction, as opposed to speed, a scalar quantity which only has size.
An example is speed may be 30km/h, and an example of velocity is 30km/h East.
Therefore two people can have the same speed and different velocities because they can be traveling in different directions.
For example, you and your friend could be doing shuttles together but you started at one wall and they started at the other, so even though you are running at the same speed, you always have different velocities because they are running in the opposite direction as you.
Hope this helped!
