Answer 1

speed tells us only about magnitude but velocity tells both magnitude and direction

Answer 2

SPEED-

》Speed is distance travelled per unit time or the rate of change of distance.

》It is a scalar quantity.

》Speed can never be zero. It can also never be negative.

》Speed has no direction.

》It never decreases with time in any case.

》It is never zero for a moving body.

VELOCITY-

》Velocity is displacement per unit tike or rate of change of displacement.
