.A crest vertical curve joining a +3 percent and a-4 percent grade is to be designed for 40 Km/h. If the tangents intersect at station (K20+ 60.00) at an elevation of 200 m, determine the stations and elevations of the BVC and EVC. Also, calculate the elevations of intermediate points on the curve at the whole stations.
