1. The problem statement, all variables and given/known data A plus 3.0% grade intersects a minus 5.0% grade at station 10+ 150 and at an elevation of 170.500 m. Given that a 500 m length of curve is utilized, determined the station and elevation of the PC and PT. Calculate elevations at every 20 m station and locate the station and elevation of the high point of the curve. 2. Relevant equations r =g2 - g1/L 3. The attempt at a solution 219 is it correct?
