A sag curve and crest curve connect a -3.5% tangent section of highway (to the west) with a +2.5% tangent section of highway (to the east). The +2.5% tangent section is at a higher elevation than the 3.5% tangent section. The two tangent sections are separated by 1150 ft of horizontal distance.

If the design speed of the curves is 50 mi/h, what is the common grade between the sag and crest curves (G₂ of sag and G₁ of crest, from west to east), and what is the elevation difference between the PVCs and PVTc?
