The grade of a highway is calculated as (vertical height / horizontal distance) * 100. Given a 36% grade, we can set up the equation (550 / horizontal distance) * 100 = 36. Solving for horizontal distance gives us horizontal distance = 550 / 0.36 = 1527.78 feet, which rounded to the nearest foot is 1,528 feet.
