Because when you look at the speedometer it is telling you your speed at that particular instant in time, it changes from instant to instant.

What is a sentence for instantaneous speed?
Instantaneous speed is, essentially, instant speed. An example sentence would be: The Camaro's instantaneous speed surprised most of the watchers.
Does a cars speedometer measure speed or velocity or both?
Yes it does, it measures miles per hour (mph) and kilometers per hour (kph), which is basically your speed. Some cars have speedometers that go up to a higher or lower speed, but don't worry about that. Also there tends to be more kilometers per hour than miles per hour on any given speedometer.
When is instantaneous speed used?
Instantaneous speed is used to describe the speed of an object at a specific moment in time. It provides information about the object's velocity at a precise instant and can be calculated by determining the rate of change of position at that moment.
Does a speedometer both measure speed and velocity?
No. A speedometer only measures speed. You also need a position sensor or direction vector coupled with the speedometer in order to know velocity, because velocity includes direction.
Does a car has speedometer velocity are both?
A car has a speedometer, which measures the speed of the vehicle in miles per hour or kilometers per hour. Velocity, on the other hand, is a vector quantity that includes both speed and direction. So while a car's speedometer measures its speed, velocity would require additional information such as direction to be fully described.

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.
Does the spedometer of a car read average speed or instantaneous speed how do you know?
To be pedantic... In a car with a digital speedometer, speed is NOT instantaneous in the sense that it is a measure of distance per unit time. It does this by measuring a change in distance over a very short period of time to *approximate* the instantaneous speed. If the time period is a small fraction of a second you wouldn't know the difference! For older cars with analog speedometers the speed is instantaneous as it directly translates the speed at which your wheels are turning.
What is the speed at any instant time known as?
Instantaneous speed is speed at any instant in time.
How do you measure the speed in NASCAR?
They measure engine speed in RPM, but car speed in MPH. If you want to know how they know how fast the cars go from the stands or the officials' booths, that is what radar guns are for. Inside the cars, the speedometer tells how fast they are going, and the tachometer tells how fast the engine is running.
Are members of highway patrol more interested in average speed or instantaneous speed?
As we know that the duty of highway patrol is to check that someone is not breaking the speed rule at highway. So they are more interested in to know that what is the instantaneous speed of your car because instantaneous speed tell about the speed of a car at any instant. They have no concern with average speed of your car.
Does a cars speedometer measure speed or velocity or both?

If the reading on the odometer of a vehicle in the beginning of a trip and after minutes were km and km respectively will the reading on the speedometer show this velocity were the vehicle i?
To determine if the speedometer reading reflects the calculated velocity, you need to know the distance covered and the time taken. If the odometer readings indicate a distance traveled and you divide that by the total time of the trip (in hours), you can calculate the average speed. The speedometer shows the vehicle's instantaneous speed, which can fluctuate based on acceleration or deceleration. If your average speed aligns with what the speedometer indicates at a specific moment, then yes, it reflects the velocity; otherwise, it may differ.

What does a cars speedometer measure?
A cars speedometer measures speed. A speedometer is a gauge that displays the speed of a vehicle so the driver will know how fast the vehicle is moving.
