Please ask that more clearly.
yes
Of course it can.If you live 10 miles from your job, and you hit 100 miles per hour on the way to the office,but stop for coffee for an hour during the trip, I guarantee your average speed is less than100 mph.
instantaneous speed
Instantaneous speed is the speed at a particular moment in time.The average speed of an object tells you the (average) rate at which it covers distance
The speedometer on a vehicle shows the instantaneous speed, which is the speed of the vehicle at any given moment. It does not display the average speed over a period of time.
Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.
Average speed is the total distance divided by the total time. Instantaneous speed is the speed at one instant, that is found by taking the first derivative of the position, and evaluating it at t (time).
A car's speedometer typically shows the instantaneous speed, which represents the current speed of the vehicle at any given moment. It does not show average speed or velocity.
Instantaneous speed is the speed of an object at a specific moment in time, while average speed is the total distance traveled divided by the total time taken. At the exact moment when an object's speed is constant, its instantaneous speed and average speed will be the same.
Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
The concept of average speed is somewhat simpler than "instantaneous speed".
If I drive away from my house at 8:00 in the morning and return at 6:00 PM that same evening with 50 more miles showing on the car, you know immediately that my average speed for the day was 5 mph. But you don't know a thing about how much of that time I was stopped, how much in motion, or what my speed was at any moment between 8 and 6, because there's no necessary relationship between instantaneous and average speed. I guess it's probably true to say that there has to be some instant during any period of time when the instantaneous speed must be equal to the average speed during the same period. That sounds like a nice theorem, and its proof ought to be good for some mathematical recreation, but it doesn't seem too useful.
