A vertical curve is required to join a road with + 2.5% grade to a road with -3% grade. The design speed of the road is 90 kmph and safe stopping sight distance is 180 m on the road. The coordinates of VPI is (500 m, 100 m), with respect to a fixed bench mark. The horizontal co-ordinate of highest point of curve with respect to fixed benchmark is m. (rounded off to two decimal place)
