Does the speedometer of a car measure its average speed ?

What does the speedometer of a car measure average speed or instantaneous speed ?

Assertion : The average speed of an object may be equal to arithmetic mean of individual speed. Reason : Average speed is equal to total distance travelled per total time taken.

The average velocity of a particles is equal to its displacement-time graph ?

Assertion :- The displacement always equals the product of the average velocity and the time interval. Reason :- The average velocity always equals the mean value of the initial and final velocities.

Assertion : On a curved path, average speed of a particle can never be equal to average velocity. Reason : Average speed is total distance travelled divided by total time. Whereas average velocity is, final velocity plus initial velocity divided by two.
