I think it is cuz speed is velocity it's just a vector (more difficult name)

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.
If a ferris wheel is rotating at constant speed is it moving at a constant velocity?
No. Velocity combines speed and the direction of motion.Constant velocity is constant speed in a straight line.In circular motion, the velocity is always changing even if the speed is constant,because the direction is always changing.
Jake and Brenda drove at a speed of 30 mph for 1 hour. Then they turned around and drove 45 mph until they were back where they started. What is true about their average speed and average velocity?
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
Total distance divided by total time?
total velocity * * * * * It is the average speed, not velocity which is a vector.
What is the acceleration in science if you know average speed and time?
If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero.
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.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its 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.
What distinguishes the measurements of speed from that of velocity and acceleration?
Velocity = speed, and the direction in which it's happening Acceleration = rate at which speed is changing, and the direction in which it's changing
How would you differentiate between speed and velocity?
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).
Can you have constant speed but change in velocity?
Velocity will always change in speed.
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).
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
Can a body have nonzero average speed but have zero average velocity give example?
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
Jake and Brenda drove at a speed of 30 mph for 1 hour Then they turned around and drove 45 mph until they were back where they started What is true about their average speed and average velocity?
their average speed is greater than their average velocity.
When is average speed of an object not equal to average velocity?
For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.
