    Question Triangle & (geometric) vectors

    In triangle ABC there is point D on line segment AB, so that |AD|:|DB|=2:1, and there is point E on BC, so that |BE|:|EC|=1:4. Point F is the point where line segments AE and DC intersect. Express the relationship (ratio) between |AF|:|FE| ( \vec{AB}=\vec{a}, \vec{BC}=\vec{b}).
