G-Nav question
Hi there,
I'd need some help with the following question:
The relative bearing to a beacon is 270°R. Three minutes later, at a ground speed of 180 knots, it has changed to 225°R (corrected! previously 255). What was the distance of the closest point of approach of the aircraft to the beacon?
Correct answer would be 9 nm.
I just can't figure it out at the moment (perhaps it's to late, should go to bed) - there must be a formula for this
Thanks!

Indeed, there seems to be an error. As the others have said, the given answer of 9 nm would make the second RB 225 degrees.
The answer to the question as it is would be 36 nm (using the 1/60 rule).

Thanks for the respond! Yes, you guys are right, the second RB is 225 not 255 - I guess that's contributed to human error, which proofs that one should be working on this type of question when it's to late (at night)!
