Um, maybe the office was on a low gravity planet, like Mars (or Vespa to be more realistic)?
On that note, here’s a similar riddle: If an Olympic high jumper can vault a bar 5 feet off the ground (on planet Earth), how high a bar can he clear on the Moon, assuming gravity on the moon is 1/6 of Earth gravity? (If you need to make assumptions in your answer, be sure to state them).
