Two ships, A and B, leave port at similar time. Ship A travels north-west at 28 knots and ship B travels at 38 knots in a direction 40° west of south. (1 knot = 1 nautical mile per hour)
(i) Determine the magnitude the velocity of ship A relative to B?
(ii) Determine the direction of the velocity of ship A relative to B?
(iii) After what time will the ships be 155 nautical miles apart?
(iv) Determine bearing of B (the direction of B's position) as relative to A at that time?
