Frames of Reference Question - Airplane Problem

  1. Aug 3, 2017 #1
    Hi, Could someone please have a look at my solution and let me know if I did it correctly.

    Thank you!!

    1. The problem statement, all variables and given/known data

    A pilot is flying from City A to City B which is 300 km [NW]. If the plane will encounter a constant wind of 80 km/h from the north and the schedule insists that he complete his trip in 0.75 h, what air speed and heading should the plane have?

    2. Relevant equations

    3. The attempt at a solution

    You have a sign error. Unfortunately, you did not type in the solution, so I can not show, where the error is.

    Your diagram is wrong. You seem to have put label C where A should be and label A where B should be.
    What direction does the resultant 400km/h need to be in?
