- What is the distance from SF to Seattle in Nautical miles? His hint was: area code of Missouri. I guessed the distance was like 1000km or roughly 700 regular miles and since a nautical mile was larger than regular mile, guessed the answer to be like 600 or 610 (in tel area code, I know enough about npa-nxx numbering to guess that the second digit was probably 0/1). He said close enough.
- At what height will the flight from SF to Seattle operate if its route is North with a little bit to the west? I know that flights to west operate at even heights plus 500 (once to east operate at odd plus 500), and most flights operate above 30k ft, so I guessed 32500. His answer was close enough.
- What is the flight time from SF to Seattle? His hint was: Baccardi minus 13. I knew there was a Baccardi 151 and so guessed 1 hr 40 min since it had to be more than 1 hr but less than 2. His answer was close enough.
