Velocity of a body is a vector quantity- meaning it has both magnitude and direction while speed is a scalar quantity where only magnitude is given.
The average change in speed is the total distance traveled divided by the time taken to cover the journey. While on the other hand, velocity can be described as the displacement of a body divided by the time taken and the direction of movement.
Hence, the only time the magnitude of velocity equals that of speed, is when a body is moving in a straight line. This is because the total distance covered will be equal to the total displacement of the body.
