60min -> 60km.
1min ->1km.
10sec ->166.
So, 9sec -> 149.5.
1min ->1km.
10sec ->166.
So, 9sec -> 149.5.

9sec=?.
Cross multipication =150m.

Let the length of the train be x.
3600/9=6000/x.
X=150m !
3600/9=6000/x.
X=150m !

1km = 1000m,
1hr = 3600s.
1km/hr = 1000/3600.
= 5/18 m/s.
1hr = 3600s.
1km/hr = 1000/3600.
= 5/18 m/s.
