Answer:
Option (A) is correct.
Step-by-step explanation:
The speed of a car is defined as the ratio of the distance traveled by the car to the time taken by the car.
speed = distance / time
The average speed of the car is defined as the ratio of the total distance traveled by the car to the total time taken by the car.
Average speed = total distance traveled / total time taken
Instantaneous speed is defined as the speed of the car at any instant.
