The

of an object consists of its speed and direction.

a. Average speed

b. Instantaneous speed

c. Velocity

d. Displacement

c. Velocity

Explanation:

Velocity is a measure of change of position of the body with time. Change of position means the distance traveled by the object in a given interval of time but in a particular direction.

We know that speed is given as the distance traveled over a given time interval without taking into account the direction of motion. So, the magnitude of velocity is same as its speed. Velocity, being a vector quantity, has both magnitude and direction.

Therefore, the velocity of an object consists of its speed and direction.
