Speed is the distance covered in unit time whereas velocity is the displacement covered in unit time. Speed is a scalar quantity and velocity is a vector. ... Speed can never be zero but the velocity can be positive, negative or zero. This is the difference between speed and velocity.

Explanation:
y.(i) Speed is defined as the distance travelled by the body per unit time
(ii) Speed = timetaken/distance travelled
(iii) Speed is always positive
Velocity :
(i) Velocity of a moving body is defined as is rate of change of its position with time in a particular direction
(ii) Velocity =
timetaken
displacement
displacement
displacement
displacement (iii) Velocity is a vector quantity
(iv) Velocity can be negative
