The speedometer in your car reads 55 mi/h. This represents the Instantaneous speed of the car.
Step-by-step explanation:
Speed is a measurement of distance and time. Speedometers have been installed in vehicles to indicate the speed at which the driver drives the vehicles and control is also been used in few vehicles for the safety of the passengers like in school buses. When the car reads a reading in the speedometer, it denotes the instant speed of the car rather than the average speed.
