document.write( "Question 357970: The safe maximum speed in knots (nautical miles per hour) of a sailboat is given by the formula: S=1.3 squares 1 where ‘S’ is the speed in knots and ‘l’ denotes the length of the waterline in feet. If the waterline length is 20 feet, what is the maximum safe speed of a sailboat?
