One hour = 60 Km,
3600 Seconds = 60 Km,
60 Seconds = 1 Km,
9 Seconds = 0.15 Km,
1 Km = 1000 Meter.
0.15 Km = 150 Metter.
3600 Seconds = 60 Km,
60 Seconds = 1 Km,
9 Seconds = 0.15 Km,
1 Km = 1000 Meter.
0.15 Km = 150 Metter.

(60 x 1000)/(60 x 60) = 150.

One more time explain me.
I cannot understand this step (6 * (5/18) * 9) = 150. Pease explains briefly.

That is (60 * (5/18) * 9) = 150.
Actually, the train speed is given in 60km/hour. We just convert that into m/sec as follows:
60km/hour = 60 * (5/18)m/sec that is equal to 150.
