The correct answer to the question is: Direction
Step-by-step explanation:
The average velocity of a body is defined as the rate of change of displacement.
We know that displacement is a vector quantity. Hence, it has magnitude as well as direction for its specification.
On the other hand, the average speed of a body is defined as the rate of change of distance travelled. Hence, the average speed of a body is a scalar quantity. It means that it has only magnitude.
Hence, during the calculation of average velocity,we have to think of its direction.
