No. The average speed is the average of the magnitude of the velocity but not the magnitude of the average of the velocity.
This is because for vectors |A + B| ≤ |A| + |B|.
Suppose you travel 100 metres due East at 10 metres per second and then 100 metres due North also at 10 metres per second. Your speed, throughout, is 10 metres per second and so that is your average speed.
But your average velocity is the total displacement vector divided by the total time. This is
100*sqrt(2) metres due NE/20 sec = 7.07 metres per second due North East.
Its magnitude is 7.07 metres/sec.

Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
How is velocity diffrent from speed?
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.
What the definitioin of speed?
The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time
Are speed and acceleration the same?
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
A velocity vector tells you two things?
Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Is distance the magnitude for average velocity?
No. Average speed is.
Is Distance the magnitude of average velocity?
No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).
Can average velocity and average speed be same?
The magnitude of both can be the same.
The magnitude of the average velocity vector?
The magnitude is the speed, such as m/s or km/h.
When is speed equal to the magnitude of velocity?
That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.
Is overall velocity the same as average speed?
No, velocity is a vector quantity (i.e. magnitude & direction) while speed is a scalar quantity (i.e. magnitude only).
How is speed difrent from velocity?
Velocity has magnitude and direction and speed only has magnitude.
What is the magnitude of velocity?
what is magnitude of average velocity
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
Does speed have magnitude only?
speed has magnitude. velocity has magnitude and direction.
When is the average velocity is equal to the instantaneous velocity?
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
