Two ships, a and b, leave port at the same time. ship a travels northwest at 24 knots, and ship b travels at 28 knots in a direction 40 degrees west of south. (1 knot-1 nautical mile per hour) what are the
(a) magnitude and
(b) direction of the velocity of ship a relative to b?
(c) after what time will the ships be 160 nautical miles apart?
(d) what will be the bearing of b (the direction of b's position) relative to a at that time?
