A boat P leaves part A (450N, 500W) and sails at an average speed of 10 knots. It sails due east along a parallel of latitude to B (450N, 420W) and then sails due north to C (480N, 420W). Another boat Q leaves D (550N, 100W) at the same time as P leaves A. It sails due west and then due south to meet boat P at C.
