Captain Jack Sparrow is looking for Davey Jones" chest. The Black Pearl leaves port at 10 am and travels due east at 25 knots. At 11:25 am Jack Sparrow changes the ship's course to S 23 degrees E and travels at 36 knots until 1:18 pm. Then the ship travels due east at 52 knots until 3:25 pm. Finally Jack Sparrow changes course to N 16 degrees E and travels at a speed of 61 knots until 6 pm when he locates the treasure. Find the distance the Black Pearl is from port when the treasure is located and the bearing from treasure back to port.
