What is a speed at a given moment?
Instantaneous Speed.
Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity.
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
velocity is the name given to speed in a specific direction.
Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
What is a speed at a given moment?
Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.
the rate at which an object is moving at a given moment in time.
The instantaneous speed is the rate of motion at any given time.

velocity
Average speed = distance/time
Actual speed is the speed you are traveling at any given moment at any given point. Average speed is figured by dividing the distance you traveled by the time it took you to drive that distance.
velocity
the rate at which an object is moving at any given moment in time. from the physical science glossary
An objects speed at any particular moment in time is known as its instantaneous velocity. This is the rate of change or the derivative of the objects position.
No, the odometer measures the distance traveled by a vehicle. The speedometer measures the speed at any given moment in time, but not the average speed.
