7. A sag vertical curve connects a-4.75% grade and a +3.75% grade. The PVI is at station 45+90.00 at an elevation of 611.00 ft. The design speed is 50 mi/h. Determine the minimum length of the vertical curve using the AASHTO method (K factors). Round the minimum length up to the next 10 ft multiple for design of the vertical curve and associated calculations. Using this length, determine: The station and elevation of the PVC The station and elevation of the PVT The station and elevation of the low point The elevation of station 44+95.00
