I just 'asked Jeeves' 55nm is 101 km. I know you're a modder Beery, did you get your info from the game files?

Excellent guide BTW.

I got the info from the game files: it just says radius = 100 and time = 2880 minutes (48 hours), then I tested it by recording the time I entered a circle with a radius of 100 nautical miles around the objective. Sure enough, exactly 48 hours after I entered that circle the mission completed. I only tested it once though, so in order to be definitive it needs to be confirmed by another player.

Note that the radius doesn't have to be 100 - it can be anything, so it's possible that some objectives might be more or less than 100nm. The only ones I've seen so far have been 100 though.
