2-13. Using data given in the sketch of the vertical curve below, calculate the sta. and elev. of the lugh point (hi/pt.) of the curve. Ans.: (a.) Hilpt. sta. $=9+79$; elev, $=46.30$ (b.) Hi/pt sta. $=9+83$; elev. $=46.32$ (c.) Hi/pt: sta. $=9+85$; elev. $=46.34$ (d.) Hilpt. sta. $=9+88$; elev. $=46.39$ 12-14. Using data given in the sketch of the vertical curve below, calculate the sta. and elev. of the high point (hi/pt.) of the curve. Ans.: (a) Hi/pt. sta. $=26+95$; olev $=107.70$ (b.) Hilpt. sta. $=26+98$; elev. $=107.66$ (c.) Hi/pt. sta. $=27+01;$ elev. $=107.62$ (d.) Hilpt. sta. $=26+04;$ elev. $=107.73$
