speed is defined as the distance travelled by an object in an interval of time.
Velocity is defined as the displacement by an object in an interval of time
The equation of motion which shows position position time relationship is S equal to UT plus half a t square

a) speed is a scalar quantity it is the ratio of distance and time where as velocity is vector quantity and it is the ratio of displacement and time speed is not dependent upon the direction and velocity is dependent upon the direction
