Final answer:
Velocity is the vector quantity among the given options as it includes both magnitude and direction, such as 30 miles per hour to the north.
Step-by-step explanation:
The vector quantity among the given options is velocity. Velocity is defined as a change in displacement over time and includes both magnitude and direction. This distinguishes velocity from speed, which is a scalar as it only has magnitude without direction. Distance is also a scalar as it does not have an associated direction. Similarly, time is considered a scalar because it only has magnitude and no direction is associated with the measurement of time.
For example, if a car travels 60 miles to the north in 2 hours, its velocity would be expressed as 30 miles per hour to the north, whereas its speed would simply be 30 miles per hour.
