Two ships, A and B, leave port at the same time. Ship A travels northwest at 20 knots and ship B travels at 28 knots in a direction 37° west of south. (1 knot = 1 nautical mile per hour;) What are
(a) the magnitude (in knots) and
(b) direction (measured relative to east) of the velocity of ship A relative to B?
(c) After how many hours will the ships be 150 nautical miles apart?
(d) What will be the bearing of B (the direction of the position of B) relative to A at that time? (For your angles, takes east to be the positive x-direction, and north of east to be a positive angle. The angles are measured from -180 degrees to 180 degrees. Round your angles to the nearest degree.)
