4. Page 24, second line, continuation:
"10 meters (33 feet)"

I got 9 km (kilometers), i.e. about 1000 times more, a reasonable result
I think the 10 meters was just an extrapolation of the 3mm/second times an hour, which does give around 10 meters. If your figure was even more teeny than that, how'd did you get 1000 times more?
It's quite simple, actually. The Coriolis force here does not change much over a 100 km distance, so we can treat it as approximately constant. Now, a constant force produces constant acceleration, and distance will be proportional to the time SQUARED. Since the deflection is 0.7 mm after 1 second, it will be (3600)^2 times larger after 1 hour. This gives approximately 9 km.

Likewise, I stand by my other results.
