Which statement best illustrates instantaneous speed?

Explanation:
Instantaneous speed is the speed of an object at a particular moment. A car's speedometer shows exactly that: how fast the car is going right now. It can change as you drive, so the reading changes with time. In contrast, average speed over a journey is the total distance divided by the total time, which smooths out any fluctuations in speed. Displacement divided by total time gives average velocity, which includes direction and also reflects overall change rather than the present moment. So the speedometer reading at a specific moment best illustrates instantaneous speed.
