9)    322 degrees from the ship forms   322-270 = 52 degree angle (at the boat 'tail' )

               tan 52 = opp/adj

               tan 52 = 18.5 / d

                   d = 18.5 / tan 52 = ~~14.5 km

      14.5 km /  48 km/hr = .301 hr      = 18 min

10)    from 10 :15   to  1:45    is      3 1/2 hours

        3 1/2 hr  x 700 km/hr = 2450 km

         compass bearing to airport is 330       30 west of north
