Distance = s * t = 60 * 5/18 * 9 = 150m.

1000m=1km so 60000m goes in 1hour.
1 hour=3600 sec so 60000/3600 =16.666 so train cross in 1 second is 16.666m...so 9 seconds 16.6666*9=150meter .
1 hour=3600 sec so 60000/3600 =16.666 so train cross in 1 second is 16.666m...so 9 seconds 16.6666*9=150meter .

60*5/18 = 50/3.
50/3 *9,
Then 50*3.
Answer = 150.
50/3 *9,
Then 50*3.
Answer = 150.

60km/hr = 5/18 * 60 m/s = 50/3 m/s.
50m/s means 50 metres for 3 seconds,
Then for 9 seconds - 150 metres.
50m/s means 50 metres for 3 seconds,
Then for 9 seconds - 150 metres.

@All.
The answer here calculated is the distance of the train travelled in 9 seconds right, then how can you claim it as the length if the train?

@All.
When we are converting km to meters, we have to take 5/18 as the options given in meters. So we have to do it.
