Here we have to think that they are asking the length of train.
First we have conform that all the values given are same format or not .
if not we have to convert them into one format depending on the answers given to us.
Then it is possible to get the correct answer.
The first answer explanation by Sundar is very good .

First convert the km into metres 60km will bcome 60000 metres then divide 60000 with 1 hour that is 60,60000/60 this will give us the speed of the train in mins n then 1000 with 60(to convert the speed in seconds)then multiply the ans with 9 seconds.ie 16.66*9 will give us 150 :)
