If you will convert Speed of the train which is 60km/hr.
Then it will be ( 150/9)m/sec,
You get the answer directly which is 150m.

Some thing is missing in the question and solution because if train crosses the pole means train will has to cross the extra length as much the length of train.

36sec ---> 600m.
9sec ------> 600 * 9/36 = 150meters.
9sec ------> 600 * 9/36 = 150meters.
