2. Given a sag vertical curve connecting a -1.5% grade with a +2.5% grade on a rural arterial highway, use the rate of vertical curvature and a design speed of 70 mi/h to compute the elevation of the curve at 100 ft stations if the grades intersect at station (475+00) at an elevation of 300.00 ft. Identify the station and elevation of the low point.
