    A ship is moving due west at 40 km/h and the wind appears to blow from 22.5 degrees west of south. The ship then steams due South at the same speed and the wind appears to blow from 22.5 degrees east of south.
    a) the true speed of the wind
    b) the true direction of the wind

    I seem to get a totally different answer
