This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
When the length of the time is decreased more and more ,average velocity of the particles equals instantaneous velocity.
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
In physics, total distance/TIME is average speed, so this is false. Velocity should be switched out with TIME.
No, you've got it backwards. The absolute value of velocity equals speed. Velocity is speed with a direction; speed is just a number, without regard to direction.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)

Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Decelerating means that the speed, i.e., the absolute value of the velocity, decreases over time.
distance over time equals the speed/velocity.
Velocity is a vector which incorporates both speed (a scalar) and direction. So the speed (distance divided by time) must increase if the velocity increases as the direction (an angular measurement) does not affect the absolute value of the vector.
