Example19.9: (a) Two ships A and B start sailing from port P at the same time. Ship A sailing at 35km/h is on a bearing of 335° and ship B sailing at 22km/h is on a bearing of 065°. Find after three hours (i) the distance between the two ships (ii) the bearing of A from B. (b) After covering a distance of 120km from the port, ship A reaching a port D then turns and sail parallel to the track of ship B. How Jong will it take shin A to reach a noint E due north of P?
