Answer:
The answer is A. its Velocity
Explanation:
The velocity is the physical magnitude that shows and expresses the variation in terms of the position of an object and as a function of time, that is, the velocity is the distance traveled by an object in the unit of time.
The velocity is then expressed with the formula where (v) is velocity (d) is distance and (t) is time
So if we know the distance traveled by an object in one hour we can calculate the velocity of the object.
