Speed is a scalar measure (ex: 5 m/s) and only has magnitude
If you add a direction to it (ex: 5 m/s East) you are making it a vector
Velocity is a vector.

Velocity is represented by a V with an arrow above
Speed is represented by either a V or a U with no arrow above (because the arrow signifies that it is a vector)
Answer: Velocity
