Compute the passing sight distance available given a $475-ft$ curve, grades

of $g1=+2\mathrm{.}00\%$ and $g2=-1\mathrm{.}50\%,$ VPI at station $96+80,$ and elevation $845\mathrm{.}26$ ft $,$ stakeout at full

stations. $($Assume $h1=3\mathrm{.}00ft$ and $h2=4\mathrm{.}75ft.)$

Express your answer in feet to five significant figures.
