There's 5280 feet in a mile. 5280x16=84,480 feet an hour. Then divide by 60 to get feet per minute. 84,480/60=1408 feet a minute. This is not one of the answers but this is correct. 528 feet a minute is 6 miles per hour. 5280 feet a minute is 60 miles per hour. The answer would have to be in between.
