Question

3.9) Two level sections of an east-west highway (G=0) are to be connected. Currently, the two sections of highway are separated by a 1200m (horizontal distance) ,2% grade.the westernmost section of highway is the higher of the two and is at elevation 30m. If the highway has a 100km/h design speed, determine, for the crest and sag vertical curves required, the stationing and elevation of the PVCs and PVTs given that the PVC of the crest curve (on the westernmost level highway section) is at station 0 + 00 and elevation 30m. in solving this problem,assume that the curve PVIs are at the intersection of G=0 and the 2% grade,that is A=2.

3.10 consider problem 3.9 suppose it is necessary to keep the entire alignment within 1200 m that currrently separate the two level sectionns.it is determined that the crest and sag curves should be connected (the PVT of the crest and the PVC of the sag) with a constant -grade section that has the lowest grade possible.again using a 100km/h design speed determine for thee crest and sag vertical curves,the stationing and elevation of the PVCs and PVTs given that the westernmost level section ends at station 0+00 and elevation 30 m.(note that A must now be determined and will not be eqaul to 2)

i only want the answer of 3.10. 3.9 is for you to refer.
