A broad gauge railway line passes through a horizontal curved section (radius $=875 \mathrm{~m}$ ) of length $200 \mathrm{~m}$. The allowable speed on this portion is $100 \mathrm{~km} / \mathrm{h} .$ For calculating the cant, consider the gauge as centre-to-centre distance between the rail heads, equal to $1750 \mathrm{~mm}$. The maximum permissible cant (in $m m,$ round off to $I$ decimal place ) with respect to the centre-to-centre distance between the rail heads is
