In scooter video activity, the scooter rider travelled only 6 km during the entire journey but we saw that the speedometer sometimes showed a speed of 5 km/hour, sometimes 20 km/hour and sometimes 40 km/hour and so on.
So the speed at any given moment, say every second, is known as the instantaneous speed.
Instantaneous speed can change with every moment or second.
However, for an object moving with constant speed, the instantaneous speed and the average speed will be the same.

Instantaneous Speed
Speedometer's reading
If you want to find out your instantaneous speed - just look at the speedometer right at that moment.
