Charlie and Alexandra are running around a circular track with radius 60 meters. Charlie started at the western- most point of the track, and, at the same time, Alexandra started at the northernmost point. They both run counterclockwise. Alexandra runs at 4 meters per second, and will take exactly 2 minutes to catch up to Charlie. Impose a coordinate system, and give the x- and y-coordinates of Charlie after one minute of running.

I have no idea how to start when I have info. only for Alexandra....

Google your question or whatever search engine you have. A university math site will come up with that question on their assignment page. The answer is at the end of the question. If you can't find it let me know.

The answer isn't the whole thing, I would like to understand how to do a problem like this, if possible. Also this question is more complex than the examples shown in my book which is why I was looking for some help.

Yes, I can certainly understand that. Sometimes teachers have to defer to other ones when they have a little less knowledge and no one is stepping up to the plate.

Why don't you post your question again? There are other teachers who may have missed the chance to help you.
