A series of vertical curves connect a 3% upgrade, a 2% downgrade, and another 3% upgrade moving west to east. These curves are designed such that they connect directly to one another (i.e., the PVT of the first curve is the PVC of the second curve). If the design speed of the alignment is 60 mi/h, what is the elevation difference between the two road segments (i.e., the vertical difference between the PVC of the first curve and the PVT...
