Certainly not.
You get into your car at 8:00 in the morning, and drive 20 miles to your office. Your car stays in the company garage all day while you work. In the evening, you get in your car and drive 20 miles back home, arriving at 6:00 PM, ten hours after you left.
Your average speed for the 40 miles in 10 hours is (40/10) = 4 miles per hour, even though your instantaneous speed was 60 or 70 at some points on the way to and from the office, and zero for most of the day, while the car sat parked in the company garage.
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
When the average velocity of a body is equal to its instantaneous velocity, it means that the body is moving at a constant speed in a straight line. This indicates that the body's motion is uniform, with no acceleration or deceleration occurring.
Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.
Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.
Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.
In uniform motion.
The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.
you are still. motion is at rest.
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
For the instantaneous value of average velocity, average speed and average velocity are equal.

An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.
Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.
