You walk 6.7 km to the east and then 10.9 km to the west.

Answer:

4.2 km West of the start

Step-by-step explanation:

Displacement is a vector quatitiy which means it has direction adn magnitude. It is the distance you are at the very end of the journey from the start.

We can assign one way as a positive direction and the other a negative and then add them

I will say that West is positive and East is negative:

(10.9) + (-6.7) = 4.2km
