Answer:
30 miles per hour North
Step-by-step explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
![Velocity = (distance)/(time)](https://img.qammunity.org/2022/formulas/chemistry/college/cmhc50edulnj1gjy9rola6klfxjnewwos9.png)
![V = (d)/(t)](https://img.qammunity.org/2022/formulas/chemistry/college/ehkfv0njb7kdojr4l2k9e4yidn1tw8qw6q.png)
Hence, 30 miles per hour North is an example of a velocity because it is a vector quantity that has both magnitude and direction.
