There is a cache that I need to add 15 seconds to the starting coordinates to get the final spot. Someone tried explaing about decimal minutes, divide by sixty, etc. and that I need to add .25 and I still screwed it up. Let's pretend I think 2 + 2=5 and use an example N 40 39.465 and W 089 34.253. I think if I see the answer I can better understand what it means. I know this sounds like I'm trying to weasle out of this, but I've tried to understand it myself and it's not sinking through the thick noggin. Thanks
