The answer to this is 756 hours. Because first you must multiply the number of miles each flight is x the miles per minute. Next you multiply that answer by the number of trips. The answer would be how many minutes, but the question asks "how many hours", and there's 60 minutes in an hour so divide that answer by 60 and that will equal 756 hours.
