--- Quote from: J.Darren on May 30, 2010, 01:37:56 pm ---The ship is travelling at a bearing of 090, and it is 90km away from the lifeboat at the time of the call of distress. The liner is also on a bearing of 315 from the ship. When you draw the diagram, you can mark down 45 degrees twice - one is between the 54 km and the 90 km, and one is between the 90km and the normal at that point. I am guessing that you have made an assumption that the ship is at a bearing of 315 from the lifeboat AFTER it has moved 54 km ...

I reckon J.Darren is correct, the problem is that everybody bar him has misinterpreted the question. The question states that "At 0600 hours the liner, which is 90 km from a lifeboat and on a bearing of 315 from the lifeboat...". All the other answers seem to assume that the liner is on a bearing of 315 from the lifeboat at 0730 hours, and not at 0600 hours.

cooldude, you've just made a computation error - everything is correct up to the bit when you somehow say that A is 133.75 km.
