SPEED
Speed is distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction.
d is the distance moved
t is the time it takes to complete the movement
VELOCITY
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of its speed and direction of motion.
d is the distance moved
t is the time it takes to complete the movement

r = d / t
where
r is the rate, or speed (sometimes denoted as v, for velocity, as in this kinematics article)d is the distance moved
t is the time it takes to complete the movement
