    it is simply an addition of vectors

    from san fran to dc, let it vector A

    from dc to boston, let vector B

    the total displacement, let vector C


    B=(900*sin 55)i +(900*cos 55)j

    i and j are unit vectors

    C = A+B

    C=5600i +737.24i + 516.22j

    C= 6337.24i +516.22j

    to solve for the magnitude of vector C

    /C/ = sqrt(6337.24^2 +516.22^2)


    = 6358.23 km
