Answer:
[tex]\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}[/tex]
Explanation:
Velocity is found by dividing the displacement by the time.
[tex]v=\frac{s}{t}[/tex]
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.
[tex]s= 1.6 \ km \ North \\t= 20 \ min[/tex]
[tex]v=\frac{1.6 \ km \ North} { 20 \ min}[/tex]
Divide.
[tex]v= 0.08 \ km/min \ North[/tex]
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.
