camber in % will be (0.15/4.5) * 100 = 3.3 %.

Slope = Rise/Fall.
Slope = 0.15/4.5,
Slope = 0.33,
Hence, Slope = 1/30.

Y = 2(x)2n/W.
0.15 = 2(4.5)2n/9.
n = 0.033 = 1/30.
Y = crown height.
x = half of width.

Slope = rise divided fall.
= 9/0.15,
= 60.

As the camber is the half-width slope so,
60 /2 = 30.
Now 1 in 30 is the answer.

15 cm crown.
9 m wide so half it is 4.5m = 450cm,
Camber= 15/450 = 1/30.
