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. |

I couldn't expect that for a single question which is having so many methods.

Length = speed × time.
60*(5/18) = 50/3
(50/3)*9 = 150.
Length = 150 metres.
60*(5/18) = 50/3
(50/3)*9 = 150.
Length = 150 metres.

1 km = 1000 m.
60 km = 60000 m.
1 hr = 3600 sec.
= (60000/3600)*9 = 150m.
60 km = 60000 m.
1 hr = 3600 sec.
= (60000/3600)*9 = 150m.

= 60×5/18.
= 300/18 (50×6=300 ,3×6=18).
= 50/3,
= 50/3×9,
= 50×3,
= 150.
= 300/18 (50×6=300 ,3×6=18).
= 50/3,
= 50/3×9,
= 50×3,
= 150.

Speed = 60 km/hr = 16.67 m/s.
Distance = Speed × Time = 16.67 × 9 = 150 m.
Distance = Speed × Time = 16.67 × 9 = 150 m.

60000 = 3600.
x = 9.
Cross multiply.
= 3600 x/60000*9.
Answer is 150.
x = 9.
Cross multiply.
= 3600 x/60000*9.
Answer is 150.

You can simply solve like this.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.
1 0mtrs/1hr * second.
1000/60 * 9 = 150.
