A Calculus Problem I've Been Working On?

Question

I have a feeling I'm doing something wrong, but here's the question:

You start walking at a point with coordinates (2,-2). You arrive at point (4,2). If you begin walking in the direction of the vector 4i + 2j and change direction only once, when you turns at a right angle, what are the coordinates of the point where you make the turn?

I'm not sure if it's the phrasing that's confusing me, but exactly how do I got about solving this problem?
