Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference.
Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.

What is final speed divided by acceleration?
Final Velocity minus Initial Velocity (all together this is the change in velocity) divided by the average acceleration will give you the time it took for the object to reach that speed.(Vf - Vi) / Aaverage = Time
Can You calculate the velocity of a fart?
Generally wind speed is measured using a cup anemometer (wind speed measuring device). The velocity of a flatulation will decrease as it leaves the anus, so to properly measure the velocity the measurement would have to be done before the exit. Theoretically you could measure the velocity of the gases by placing a miniature cup anemometer with walls inside the rectal tract close to the anus to give an approximate wind speed (velocity) of the gases.
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.
Give me an example of average speed?
If I walk 4 kilometers in an hour, my average speed during that hour was 4 km/hour. My instantaneous speed may well have been faster at times, and slower at other times, 4 km/hour is only the average.
What is the frequency of a periodic wave if its wavelength is 2m and velocity is 12?
Frequency = (speed)/(wavelength) = 12/2 = 6 per second = 6 Hz.Note:The question doesn't give enough information to describe the velocity. "12" is nota velocity, but it can be a speed, and we've assumed that it is. Fortunately, 'speed'is all we need to answer the question.
What does instantaneous speed include?
Instantaneous speed is your speed in a given moment. The speedometer in your car and the radar gun that cops use both give a value in instantaneous speed. The disctinction here is to not confuse instantaneous speed with average speed, which is calculated over a set distance. To calculate average speed (V) you need to divide the distance travelled (D) by the time of travel (T). V= D/T

How is acceleration calcuated?
Dividing change of velocity by the time it takes to change the velocity. If acceleration is not constant, this will give you the average acceleration during the period; to get the instantaneous acceleration, you have to take the derivative of the velocity.
Why is speed vital part of expressing velocity?
"Speed" is the name we give to the magnitude of velocity ... the 'size' of the velocity, without its direction.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.
How do you find instantaneous velocity from position time graph?
You can't, since the slope of the graph means average velocity and the area of the graph has no meaning. The only way to find instantaneous velocity from position-time gragh is by plugging the data into the kinematic equations to get the answer. Edit: Actually you can if you take the derivative of the equation of the curve it will give you the equation of the velocity curve
Does the speedometer of a car read average speed or instaneous speed?
In a car, the speedometer measured Instantaneous speed. This comes from the assumption that the car does not slow down and speed up fast enough for the speedometer to be able to give an average of the changing speed.
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,
What does the slope of a distnace-time graph give you?
It gives you the speed. (not the velocity)
The displacement covered by a body in unit time is called velocity?
No. It's called the 'speed' of the body. It's the size of the velocity, but it's not complete informationabout the velocity. If you also give the direction of the displacement, then that information, alongwith the speed, defines the velocity.
What is a sentence for instantaneous?
most computer software will give an instantaneous response
If a car moves at constant speed also moving at constant velocity give an example?
A car moving at constant speed in a straight line is also moving at constant velocity.
