In a Northwest Washington County, the speeding fines are determined by the formula: F ( s ) = 13 ( s − 45 ) + 60 where F ( s ) is the cost in dollars of the fine if a person is caught driving at a speed of s miles per hour. If a fine comes to a total of $ 476 , how fast in mph was the person driving? m p h
