The course of a ship or plane is the
angle measure clockwise from due
North.
An airplane travelled on a course of 210
A ship travelled on a course of 110
Match each compass direction with a
course:

The bearing from A to B is 110 .
What is the bearing from B to A?
Draw the diagram:
A ship travels on a course of 2 1 0 .
Then it changes course to due North.
How far is the ship from the starting
point?
Draw the diagram:
A plane travels on a course of 320
then changes course to 200 . How far
is the plane from the original starting
point?
Ship A sights Ship B on a
bearing of 0 9 7 .
Make a sketch and give the compass
reading of Ship A from Ship B.
A plane flies 600 km on a course of
300 degrees. It then flies south for a
while and finally arrives on a 40
point. Find the total distance
traveled.
Town T is 8 km northeast of village V.
City C is 4km from T on a bearing of
150 degrees from T. What is the
bearing and distance of C from V?
From an iron gate, proceed 500 m
northeast to the brook, then 300 m
east along the brook to an old mill,
then 200 m S15 E to a post on the
edge of Wiggin’s Road, and finally
along Wiggin’s Road back to the iron
gate. Find the area of the region.
