Oh conspiracies...

While browsing the internet I came across this YouTube video from earlier this year.

Even if you can't sit through the 12 minutes, the claim is that the North Pole is moving at a rate of 160 miles every 6 moths. My algebra classes certainly have been working on conversions this year, so my question is, according to this claim, how many inches is the North Pole moving per second? Assume 30 days in a month.
Now whether or not you believe this is true, I'll leave up to you....
