When describing the velocity of an object, you must specify the both the speed and the direction.

That's because velocity is a vector: it has both magnitude (speed) and direction.

If you say that a object is travelling southwest at 70 km/s, you are giving its velocity.

If you say that it is travelling at 70 km/s, you are giving its speed.
