Help. not a clue

  1. Nov 7, 2005 #1
    relative motion. I've not a clue.

    OK I really need help with this problem. I don't even know where to start. If someone could just point me in the right direction, I'd appreciate it. I just need to know where to start. thanks.
    Ships A and B leave port together. For the next 2 hrs, ship A travels at 20 mph in a direction 30 degrees west of north while ship B travels 20 degrees east of north at 25 mph.
    What is the distance between the 2 ships two hours after they depart?

    Just find out how far each ship goes and then find its displacement from where it started in vector form. Once you get those two, subtract one from the other tro find the distance.
