answer question 22 only The image presents a series of questions regarding a vertical crest curve design in road construction. Below is a transcribed version suitable for an educational website focused on civil engineering:---**Vertical Crest Curve Design Analysis**You have designed a vertical crest curve which joins a +3% grade and a -4% grade. The design speed is 60 mph and you have determined the curve to be 1100 ft long. Now, you need to determine the layout of the curve when the BVC (Beginning of Vertical Curve) is located at station 12+50 ft and has an elevation of 825 ft.**Questions:**17. **What is the stationing (ft) of the PVI (Point of Vertical Intersection)?**18. **What is the elevation (ft) of the PVI?**19. **What is the stationing (ft) of the EVC (End of Vertical Curve)?**20. **What is the elevation (ft) of the EVC?**21. **What is the vertical distance (ft) between the PVI and the road surface?**22. **What is the elevation (ft) of the road surface at the same stationing as the PVI?**23. **What is the elevation (ft) of the road surface at station 14+00?**24. **What is the stationing (ft) of the high point of the road?**25. **What is the elevation (ft) of the high point of the road?**---These questions guide the analysis of vertical curves by determining specific points of interest such as stationing and elevation, essential for ensuring road safety and effective design.There are no graphs or diagrams in the image.
