Explanation:
The total distance travelled by an object divided by total time taken is called the speed of an object. Its formula is given by :
[tex]s=\dfrac{d}{t}[/tex]
Speed is a scalar quantity. It has only magnitude but no direction.
The total displacement of the particle divided by total time taken is called the velocity of that object. It is given by :
[tex]v=\dfrac{D}{t}[/tex]
D is the displacement or shortest path covered
Velocity is a vector quantity. It have both magnitude and direction.
Both speed and velocity of an object are same. The only difference is that the speed is a scalar quantity while the velocity is a vector.
The statement that best explains the difference between velocity and speed is (A) i.e. "Velocity is speed with a direction".
