Wrong. He suffocated from lack of oxygen in a few seconds (no wind)Quote:

what kind of bike was he riding? :w
I am almost done with my calculations... Is he travelling east or west on either trip?
I need to take into account the Earth's rotation and make adjustments for the time zone.
To travel 2 miles at 20 MPH you need to cover 2 miles in 6 minutes. As you took 6 minutes to cover 1 mile, it is impossible to average 20 MPH. The answer to your question is "infinitely fast"
I think his tire pressure was 57 psig.
