Question: An equal - tangent sag vertical curve is designed for 5 0 MPH . The low point is 2 5 7 ft from the PVC

An equal-tangent sag vertical curve is designed for 50 MPH. The low point is 257 ft from
the PVC at station 112+37 and the final offset at the PVT is 18.355 ft.
Find: If the PVC is at station 110+00, what is the elevation difference between the PVT and a
point on the curve at station 111+00?
