Any ideas?

anonymous · Answer

o km?

skullpatrol · Answer

Why would you say 0 km?

anonymous · Answer

could it be 13???

skullpatrol · Answer

Please don't guess, I want to help you learn how to do this question by yourself. So explain why you give an answer...

anonymous · Answer

I didn't guess I thought it was 13 because I added them all up and got 13.

skullpatrol · Answer

Oh, thanks for the explanation, that helps me understand your reasoning...

skullpatrol · Answer

Have you tried drawing a diagram of the "displacements"?

anonymous · Answer

I don't know how to draw a diagram I didn't know we were suppose to. I don't even know were I would put them on a graph and I don't even know what km means?

skullpatrol · Answer

Those are all very good questions that you need to figure out to answer this question. Let me start by saying that "km" means "kilometer" which is a measurement of distance, remember?
