Thread: Trigonometry: bearing problems

I don't even know where to start with this problem...I know that i will end up drawing a triangle....but I could really use some assistance...I think that I did number 33 right, but i'm not quite sure

Hello, aikenfan!

(31) A ship leaves port at noon and has a bearing of S24°W.
The ship sails at 20 knots.
How many nautical miles south and west will the ship have sailed by 6 pm?

Code:

                P
                *
               /|
              / |
             /  |
            /24°|
           /    |
      120 /     |
         /      |
        /       |
       /        |
      * - - - - *
      A         S

The ship leaves the port at 12 noon and sails at 20 knots.
. . In 6 hours, it has sailed 120 nautical miles to

We have: .

. . Therefore, the ship sailed about 109.6 nautical miles south.


We have: .

. . Therefore, the ship sailed about 48.8 nautical miles west.

Thank you very much! I just have one more question...for number 32....how do i do this if it gives a time (rather than a distance)?

Hello again, aikenfan!

For number 32....how do i do this if it gives a time (rather than a distance)?

Well, they did give you a distance . . . indirectly.

The plane flew for 1.5 hours at 600 mph . . . That's 900 miles.
