When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.
Velocity is a vector quantity(it has a direction). Simply use the vector adding method to combine velocities.
Uniform velocity
Velocity=displacement(distance)/time.
By vector addition

There is no such thing as zero velocity. Only zero velocity relative to some other thing. And you may have to consider rotational velocities as well.We would only know absolute velocity if we knew the positions and velocities of all the matter in the universe. But ordinary mortal problems do not usually need this, so relative velocity is all we know about.

speed is not a vector. Velocity is a vector. speed can also be used for angular velocity (which is a vector). Speed is sort of a catch all word that can cover all poorly defined velocities.
Velocity is a vector, you can sum velocity in terms of direction components such as x and y.
By vector addition
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
Navigators need to be able to combine the marine vessel's velocity with that of the any currents to arrive at the resultant speed and direction. This requires addition of the vectors representing the velocities of the vessel and of the current. It may also be necessary to add the wind velocity.
It isn't clear what you mean by the "height of a velocity".
