Solution

The correct option is B
150

Step 1:- Given data
$s p e e d = 100 k m h^{- 1}$
Step 2:- To calculate the distance covered by the train
$S p e e d, ν = \frac{d i s \tan c e (s)}{t i m e (t)}, 1 \frac{1}{2} = \frac{3}{2} S = v \times t = 100 k m h^{- 1} \times \frac{3}{2} h S = 150 k m$
Hence option B is correct
