A +2 percent grade on an arterial highway intersects with a -1 percent grade at station (535 +24.25) at an elevation of 300 ft. If the design speed of the highway is 65 mi/h, determine the stations and elevations of the BVC and EVC, the elevation of each 100-ft station, and the high point. Use L = KA.
