Homework Help: Trig question

  1. Jan 13, 2009 #1
    1. The problem statement, all variables and given/known data

    A ship in distress sends up flares that are visible to two other ships. The athabasca notes that the flares are a N41 degrees E of its position. The Britiannia, which is 12.7 nautical miles due east of the athabasca sees the flares at a bearing of 310 degrees. will the athabasca or the britannia reach the ship in distress first if they travel at equal speeds. Where do I start.

    2. Relevant equations

    3. The attempt at a solution

    Start by drawing a picture!:smile:

    I suggest putting the athabasca at the origin, letting North represent the positive y-direction and East, the positive x-direction.

    Then label the position of the Britiannia and draw a vector pointing from the athabasca in the direction N 41 deg East and from the Britiannia at a bearing of 310 degrees. The point where those two vectors intersect is the location of the ship in distress. Find that location, then calculate which ship is closer.
