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.
Yea it is.
Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
For the instantaneous value of average velocity, average speed and average velocity are equal.
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)

No, the absolute value of speed does not equal velocity. Speed is a scalar quantity that represents the rate at which an object is moving, while velocity is a vector quantity that includes both speed and direction. The absolute value of velocity is the speed of the object.
mph or 'miles per hour' is a unit and can equal any value of speed or 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.
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.
Speed and velocity become equal when an object is moving in a straight line without changing direction or when it is moving at a constant speed. Velocity is a vector quantity that includes both speed and direction, so if the direction of motion is constant, speed and velocity will be the same.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
Speed is the absolute value of velocity, meaning it does not take into account the direction of motion. Velocity, on the other hand, includes both the speed and the direction of the body's motion.
Yea it is.
