Recall the definitions: Speed is a scalar quantity that only has magnitude (how fast an object is moving), while velocity is a vector quantity that has both magnitude and direction (how fast and in which direction).
Examine each option to identify whether it includes a direction or not. If the quantity includes a direction (like north, east, southwest), it represents velocity.
Look at the first option, which is '60 km/h' without any direction specified. Since it only gives magnitude, this is an example of speed.
The other options include directions (north, east, southwest), so they represent velocity, not just speed.
Therefore, the example of speed rather than velocity is the quantity that only specifies the magnitude without direction.
