In order to find the average velocity, we need to calculate the total displacement and divide it by the total time taken.
Given that you walked 800m north, 600m east, and 200m south, we can combine the north and south displacements to get a net displacement of 800m - 200m = 600m north.
To calculate the total time taken, we need to determine the time taken for each individual displacement.
For 800m north:
Distance = 800m
Speed = 1m/s
Time = Distance/Speed = 800m/1m/s = 800s
For 600m east:
Distance = 600m
Speed = 1m/s
Time = Distance/Speed = 600m/1m/s = 600s
For 200m south:
Distance = 200m
Speed = 1m/s
Time = Distance/Speed = 200m/1m/s = 200s
Total time taken = 800s + 600s + 200s = 1600s
Now, we can calculate the average velocity:
Average velocity = Total displacement / Total time taken
= 600m north / 1600s
= 0.375 m/s north.
Therefore, your average velocity is 0.375 m/s north.
