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. The magnitude of the velocity - its absolute value - is its speed.
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.
For the instantaneous value of average velocity, average speed and average velocity are equal.
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
equal
the absolute value of negative 7 is 7 and the absolute value of 7 is also seven so they are equal. Therefore, the absolute value of negative 7 is not less than the absolute value of 7. Remember that absolute value means the positive of a number
Ye.s
This is because speed is defined as the absolute value of velocity - irrespective of the direction of motion.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
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.

no
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.
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.
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.
mph or 'miles per hour' is a unit and can equal any value of speed or velocity.
