A $-2\mathrm{.}5\%$ grade meets a $+3\mathrm{.}4\%$ grade at station $45+20\mathrm{.}5$ feet $(V).$ The elevation of the V is $895\mathrm{.}60$ feet. Use an equal tangent, $500-$foot vertical curve.

a$)$ Find the station of low point.

b$)$ Tabulate elevations for the BVC$,$ EVC, low point and each full station; check by second differences.

Remember that you need to include the low point in your tabulation.

Note: In your calculations, find your $"r($in $\%$ of stations$)"$ with two decimals. Also find all layout table calculations with two decimals$*$
