Here's an example of a remote association of three words: SALT DEEP FOAM. Can you think of a single word that can be closely associated with all three of these words? Before reading on, try to think of that word.
I hope you thought of the word SEA, as in sea salt, deep sea, and sea foam. Now think of remote associations for the following six triads:
FISHING DANCE NORTH
COTTAGE SWISS CAKE
WHISTLING CSA CUP
HOUSE WATCH BRAIN
STORM OPPORTUNITY DRESSING
HEAD MOUNTAIN GEM
A and B (the last three digits of latitude and longitude, respectively) are expressed thus:
A=ab+10a+b/2 B=(a-b)(a-b)+10b+2
You will need to figure out the numeric values of a and b; those values have something to do, of course, with your answers to the six remote associations. But what, exactly?
