To Find: To find the distance from the port.
Answer to Problem 44E
The required angle and distanceis
Explanation of Solution
Given information: The speed of the given ship is 8knots.
Formula used:Cosine and Sine formulae are used
Calculation:
Let the port is at point A, ship changes course at point B and the ship be at point C at 4p.m.
Therefore,
Using cosine formula,
Let AC
Thus, distance of ship from port is 23.88 nautical miles.
Also, let the bearing angle be y
Therefore, using sine formula,
Hence, the bearing angle is
