That's 100" traveled per pedal revolution, not mph or whatever.
Alright, I crunched some numbers from first principles.
At 52:14 gear ratio, one revolution on my peddle is 3.714 revolutions on the rear wheel. For a 27in wheel, that's 100.28inches of travel which is 2.547metres.
Logs from the Toronto Cycling App shows that my average speed range from 12km/hr to 16km/hr. So my peddling ranges from 78rpm to 104rpm. Close to the estimate I did at my desk at 84rpm.
