for expressing bearing starts with a north-south line and uses an
acute angle
to
show the direction, either east or west from this line.
S 31° E
N 52° W
N 42° E
S 40° W
Ex2: Solving a Problem Involving Bearing (Method 2)
A ship leaves port and sails on a bearing of N 47° E for 3.5 hr. It then it turns and sails on a
bearing of S 43° E for 4 hrs. If the ship's rate of speed is 22 knots (nautical mph), find the
distance that the ship is from port.
** d = rt
Classroom Ex2: A ship leaves port and sails on a bearing of S 34° W for 2.5 hr. It then returns
and sails on a bearing of N 56° W for 3 hr. If the ship's rate of speed is 18 knots. Find the
distance that the ship is from port.
