Bill drove 5,471.2 miles from Florida to Canada. It took him a total of 10 days to make the trip. If he drove the same amount every day, how many miles did he drive per day?

To find out how many miles Bill drove per day, divide the total distance by the total number of days he drove: 5,471.2 miles / 10 days = <<5471.2/10=547.12>>547.12 miles/day. Answer: \boxed{547.12}.
