The design speed of a two-lane two-way road is $60 \mathrm{~km} / \mathrm{h}$ and the longitudinal coefficient of friction is 0.36 . The reaction time of a driver is 2.5 seconds. Consider acceleration due to gravity as $9.8 \mathrm{~m} / \mathrm{s}^{2}$. The intermediate sight distance (in $\mathrm{m},$ round off to the nearest integer) required for the road is
