Answer is in meter so we have to convert the speed in m/s.

Here, R=v*v/g(e+f).

R = 60*60/127(.07+.15) = 128.8.

What is 'F' and 'e'?

You are correct @Amrit.

R min= V * V/127(e+F).
= 60 * 60/ 127(0.07+0.15),
= 128.8.
May be the correct answer 131m.

0.07 for plain and rolling.
0.10 for the hilly area.
0.04 for urban roads and frequent intersections.

The e equals v*v/225R put e equation 0.07 find R.
It is 228.57 as this question is saying about design speed so above formula will be used.

Here, the value of V^2/Rg should be under 0.25.

V = √ 27.94 R.
Underroot of (27.94 multiply by 27.94)
