The way I would solve this is by first solving how many feet by hour is in a minute. To do this, multiply 6,192 by 60, since there are 60 minutes in a hour, and you know that there should be an increase in number. That makes 371,529 feet per minute. Next, there are 60 seconds in a minute, so multiply by 60 again. That gives you 22,291,200 feet per second.
