Today in the daily report from our manager we were asked “On average, how far will the average office chair with wheels travel this year?” I treated it like an interview question and tried to figure it out before I looked up the answer at the end of the report.

  1. Assume you move your chair every fifteen minutes 1 meter.
  2. In one day you would move 32 meters. I rounded up to 50 meters to make the calculations easy.
  3. In a month you’d move about 1000 meters. In a year you’d move about 12000 meters or 12 kilometers or 7.5 miles.

And the actual answer is:

According to a recent study by the office furniture industry, the average office chair with wheels will travel 8 miles in any given year.

Too bad in real interviews these kind of questions usually leave me stumped.
