the information given is in the picture

I have to prove that BE:EF = 1:2, and also that CD:DF = 1:1

sorry if it is drawn badly, I did it quickly..but you get the idea.

This needs to be a vector proof. So i'm assuming it has to have something to do with linear independence, thought I don't exactly know how to do it. I'd appreciate if anyone could help me out.
