My BrainBashers electronic world atlas has developed another fault.
I listed six countries, and how far away each was from England, and here are the results:
Spain 14,000 miles
Fiji 12,000 miles
Germany 18,000 miles
Brazil 16,000 miles
India 16,000 miles
Iceland --,--- miles
Hint
The code has just four letters, A, B, C, and D. Each letter encodes 5 different letters.
Answer
I think, therefore I am.
Reasoning
A represents a, b, c, d, and e.
B represents f, g, h, i, and j.
C represents k, l, m, n, and o.
D represents p, q, r, s, and t.
E represents u, v, w, x, and y.
