Answer:
![\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}](https://img.qammunity.org/2022/formulas/physics/high-school/kbdn8zc0xmqu5876tjt50z1eejnz3h5a6o.png)
Step-by-step explanation:
Velocity is found by dividing the displacement by the time.
![v=(s)/(t)](https://img.qammunity.org/2022/formulas/physics/high-school/4yzlcgwc37kif9jc6wdmlmqqqgv3dn83aq.png)
where s is the displacement and t is the time.
The displacement is 1.6 kilometers, but it needs a direction as well. The question notes you walked North. The time is 20 minutes.
![s= 1.6 \ km \ North \\t= 20 \ min](https://img.qammunity.org/2022/formulas/physics/high-school/srwk3bx0r6edq0bt8b1zwjznlxz185wc7c.png)
![v=\frac{1.6 \ km \ North} { 20 \ min}](https://img.qammunity.org/2022/formulas/physics/high-school/z1jk7xlr7cjkgzbfvnib8xyzcqi8q7apa7.png)
Divide.
![v= 0.08 \ km/min \ North](https://img.qammunity.org/2022/formulas/physics/high-school/xc2l5zxh40jp2ranmqjbv4ygiifw1nx007.png)
Velocity is a vector quantity, so that is why it has the measurement and the direction.
The average velocity is 0.08 kilometers per minute North.
