Probably determined by the method used for enforcement. It refers to the speed you are going when the radar gun pings you (instantaneous speed) or the time it takes to cover a predetermined distance from an aircraft (average speed).

The above refers to enforcement, as indicated. And it is correct. As regards enforcement. The to the question is that the speed limit sign refers to the maximum instantaneous speed at any point in your travels on a roadway that is so marked.

The speed limit sign typically refers to the maximum allowable instantaneous speed that a vehicle can travel at any given moment on that road. It is not an average speed limit. Drivers are expected to adhere to this maximum speed limit at all times while driving on that road.

How is instantaneous speed different from average?

The average speed is the speed that it takes to travel a certain distance in a certain time. Average speed is determined by dividing the distance traveled by the time taken to get there. Instantaneous speed is a certain speed at any given time.


Does the speedometer of a car read average speed or instantaneous speed?

instantaneous speed


What is the difference between instantaneous speed and average speed?

Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance


Does the speedometer on a vehicle show the average speed or instantaneous speed?

The speedometer on a vehicle shows the instantaneous speed, which is the speed of the vehicle at any given moment. It does not display the average speed over a period of time.


How are average speed and instantaneous speed alike?

Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.


Is a car's speedometer show instantaneous speed average speed or velocity?

A car's speedometer typically shows the instantaneous speed, which represents the current speed of the vehicle at any given moment. It does not show average speed or velocity.


What is the same instantanoeus speed and average speed?

Instantaneous speed is the speed of an object at a specific moment in time, while average speed is the total distance traveled divided by the total time taken. At the exact moment when an object's speed is constant, its instantaneous speed and average speed will be the same.


What do you mean by instantaneous speed?

Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.


Can instantaneous speed and average speed ever be different for a moving object?

Of course. When you're driving on the Interstate and you see a State Police cruiser coming up behind you, you stomp the brake and slow way down to the speed limit. Now your instantaneous speed is only the speed limit. You feel like you're crawling, you can't stand it, and as soon as you're sure he can't see you and doesn't care, you let your car come back up to normal speed again. Your average speed for the trip, or for any whole hour that includes that little episode, is comfortably in excess of the limit, although your instantaneous speed at any instant during those few minutes was exactly the posted limit.


Why do you use average speed?

The concept of average speed is somewhat simpler than "instantaneous speed".


To justify with calculation average speed is equal to instantaneous speed?

Average speed is calculated by dividing the total distance traveled by the total time taken. Instantaneous speed, on the other hand, is the speed at a specific moment in time. They can be equal in situations where speed is constant over time, but in most cases, they will differ because instantaneous speed can vary as the object moves.


What are the similarities between average speed and instantaneous speed?

Both average speed and instantaneous speed are measures of how fast an object is moving. Average speed is calculated over a specific time interval, while instantaneous speed is the speed of an object at a particular moment in time. Both can be used to describe how quickly an object is changing position.
