180 metres
324 metres
150 metres
Answer: Option
Explanation:

Speed = 60 x 5 m/sec = 50 m/sec.
18 3

Length of the train = (Speed x Time).

Length of the train = 50 x 9 m = 150 m.

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.

= 9/3600*60*1000.

= 9 seconds/3600 seconds (We convert hours to seconds).

= 60*1000 (Convert KM to M).

= 9/3600*60000 = 150 M.

Distance = Time *speed.
1km =1000Meteres,
1hr =3600 seconds,
Distance = 60*9/3600 =9/60 km,
Distane in Metres =(9/60)*1000 =150M.

For converting km to m 60*1000 = 60000m.
For converting hrs. to sec. 60 * 60 = 3600sec.
60000/3600 = 16.6666.
16.666 * 9 = 150.

3600sec = 60*10^3m.

9sec = ?.

answer = 9*60000/3600 = 150m.

Its very simple,
But I like your methods of solving for answer.

60km = 60000m.
1hr = 3600sec.
Now, if 60000m = 3600sec,
x = 9sec.
x = 60000m * 9sec/3600sec.
x = 150m.

Speed = (60*(5/18)) divide 60&18 by 6, then,
Speed = (10*(5/3)) multiply 10 & 5,
Speed = (50/3).

That's all @Qaazi.

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.
