We will find that his average velocity is 1.11 m/s north-wise.
<h3>
How to get the average velocity?</h3>
We define average velocity as the quotient between the displacement and the time it takes to make that displacement.
We know that he starts at the point 0m, where this measures distance in the north direction.
Then he moves 1000 meters north, so the new position is 1000m.
Then he moves 200 meters south, so the new position is:
1000m - 200m = 800m.
The displacement is equal to the difference between the final position (800m) and the initial position (0m).
D = 800m - 0m = 800m.
And we know that it takes 12 minutes to walk that distance. Because we want the average velocity in meters per second, we write:
12 minutes = 12*(60 seconds) = 720s
Then the average velocity is just:
AV = (800m)/(720s) = 1.11 m/s
And the direction of this average velocity is north-wise.
