Answer:
Step-by-step explanation:
Instantaneous speed is the speed of an object at a given point of time. While the speed we usually calculate is the average speed of the object throughout its journey, instantaneous speed can be determined by calculating the derivative of the average velocity of the object in question.
And the formula for average velocity is
V(avg)= Metre/ second, which is distance/time
Hence its derivative would be
dV(avg)=d(Distance)/d(time) which is the instantaneous speed of the object
