The runner would be running at 6.67 miles per hour. This is answered by dividing 60 (minutes in an hour) by 9 (minutes it took for one mile). You are basically saying that the runner will run a mile every 9 minutes, so how many '9 minutes' (each mile ran) are in an hour.
If you run a mile in 4 minutes and 45 seconds you are averaging 12.63 miles per hour.
