The Beaufort Scale was devised in 1805 to measure wind speeds. The scale is numbered 0 to12 and represents wind speeds in the open 33 feet above the ground. The Beaufort Scale, B, can be modeled by the function B = 1.9 √ x + 8 − 5.4 where x is the speed of the wind in miles per hour. If the wind measures 55 miles per hour, what would the Beaufort Scale be?
