NAME: Rational Equation Applications 1600 1. A transportation engineer uses the formula, R = 15 + 127e , to determine the minimum radius of curvature (R) in meters, for a roadway with a 40 km/hr design speed and a maximum superelevation rate (e). What is the maximum superelevation rate recommended if the radius of curvature is 400 meters? Show your work. Round your answer to two decimal places. 2. Your camera determines the focal distance required for your picture to be in focus using the 1 1 1 lens equation, - - = , where the focal distance to the object from the lens (D) is related to the focal length (F) and the distance from the lens to the film (S). If an object is placed 6 cm from a lens with a focal length of 3 cm, how far from the lens is the image (film) formed? Show your work. Be sure to label your
