An equal-tangent crest vertical curve is designed for 45 mi/h. The high point is at elevation 380.10 ft. The initial grade is +1.90% and the final grade is -3.10%. What is the elevation of the PVT? You answer must be in ft and rounded to the second digit (e.g., 0.00), if you need to use values from tables, use "design" values (usually last column), not "calculated"

Just do question 2

An equal-tangent equal tangent vertical curve connects a +2.10% initial grade and -2.70% final grade. The PVT is at station 127+18 and elevation 206.52 ft. If the design speed is 75 mi/h, what is the elevation of the curve at station 121+58? You answer must be in ft and rounded to the second digit, if you need to use values from tables, use "design" values (usually last column), not "calculated".
