Answer:
Vector
Step-by-step explanation:
A vector quantity has both magnitude and direction. 60 mph west has a magnitude of 60 mph (the speed) and a direction of west. In contrast, a scalar quantity has only magnitude. Speed, time, distance, mass, temperature, etc. are examples of scalar quantities. They only describe how much of something, not which direction. Since 60 mph west has both a magnitude (60 mph) and a direction (west), it is a vector quantity rather than a scalar quantity. Describing both speed and direction makes it a vector.
