It's a question on my exercises and I'm not sure of the full answer.

If I use the centre of a compass rose as my waypoint, I can read off it
constantly from my GPS.

If a reading is 098T, distance 1.2m , as in the question then

I am the reciprocal of that ? right ?
Or do I have to account for variation from GPS to chart? or is that a red
herring?

I hate these questions - I always tie myself in knots suspecting a trip wire
in them and then I can't see straight.
