an air plane takes a circuitous route. the journey is split into 4 sections.
d1= 6000km (30.0 n of e)
d2= 5600km (NW)
d3= 4500km (35.0 S of W)
d4= 7000km (12.0 W of S)
 Find the resultant displacement of the air plane
what do i do, and what is the coreect answer for the planes resultant?

You add the vectors. I recommend break each of the distances into N and E vectors, so adding the four vectors can be done in components. I will be happy to critique your thinking or work.
