The average speed of the vehicle relative to the road.
instantaneous speed
instantanous speed
The speed of the car.
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.
Speedometer can determine a car's normal and maximum speed.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
It indicates the speed of the car.
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.
The speedometer in a car runs based off the speed of the transmission. The gears in the transmission spin at a known rate for the speed the vehicle is traveling at. The faster the gears spin the more the speedometer goes up. If a person replaces stock tires with larger tires, then the tires will spin slower, which will cause the speedometer to read at a value that is less than the actual speed.
Your speedometer is broken.

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.
