A plane flies from place O to place A, a distance of 300 kilometres in one hour, A being due north of O, then OA in Fig. represents the first hour of flight. It then flies from A to B, a distance of 400 kilometres during the second hour of flight, B being due east of A, thus AB in Fig. represents its second hour of flight.
