It is a vector. It is the directed straight line distance, or displacement, between two points on the path of movement (even though the actual path may be curved) divided by the actual time taken to move from one point to the other.
The reason that it is a vector is that the direction traveled is important: it is possible that part of the motion was in the opposite direction from other parts.

velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Direction. Velocity is a vector, speed is a scalar.
No. It is a speed (a scalar) but not a velocity (a vector).
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.
A scalar times a vector is a vector.
