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

I am almost done with my calculations... Is he travelling east or west on either trip?

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"
