Question

A vertical parabolic curve is to be used as a crest curve, and it is desired to know the location and elevation of the high point. The curve is 550 feet long and a grade of +3.6% intersects a grade of-4% at station 40+80.00. Calculate the high point of the curve if the intersection at station 40+80.00 is at elevation of 625 feet.
