An equal-tangent crest vertical curve connects a +3.2% and a -1.1% grade. The PVI is at

station 98+20. Due to drainage considerations, the highest point of the curve is at station

100+79.35. Determine the station of the PVC and PVT, and the design speed of the curve.

The correct answers are... what is the procedure to solving this problem

92+89.05, 103+51.05, 70 mph
