Q1:

The total value of extra widening required at a horizontal curve on a two lane hill road of radius 42 m for a design speed of 50 kmph and for vehicles with wheel base 6 m, is

A 0.500 m

B 0.589 m

C 1.089 m

D 0.089 m

ANS:C - 1.089 m

@Gayatri Meesala.

You put V in kmph.

All other units in meters.
So you can change the speed in m/s by multiplying 5/18.
Then you will get the exact answer 1.089m.
