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. |

Does the formula of the length of the train is (Speed*Time)?

= 9/3600*60*1000.
= 9 seconds/3600 seconds (We convert hours to seconds).
= 60*1000 (Convert KM to M).
= 9/3600*60000 = 150 M.
= 9 seconds/3600 seconds (We convert hours to seconds).
= 60*1000 (Convert KM to M).
= 9/3600*60000 = 150 M.

1 sec = 5/8 m.
36 sec = 5/18*36 = 10 m.
36 sec = 5/18*36 = 10 m.

1000/60 = 16.666.
= 16.666x9 = 150.
One more 1000/10 = 100.
= 60/10 = 6.
= 100 mtr/6 sec.
= 50 mtr/3 sec.
So 150 mtr in 9 sec.
= 16.666x9 = 150.
One more 1000/10 = 100.
= 60/10 = 6.
= 100 mtr/6 sec.
= 50 mtr/3 sec.
So 150 mtr in 9 sec.

Time = Distance/Speed.
From this Distance = Time*Speed.
= 9*(60*(5/18)) = 149.9999.
= 150.
From this Distance = Time*Speed.
= 9*(60*(5/18)) = 149.9999.
= 150.

How 1 hr can be written as 5/3 km/hr?
Tripta said:

1 km = 1000.
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?

Easy to improve our knowledge.
1 hour = 3600 secs.
1 km = 1000 m.
3600/1000 = 36/10 = 5/18.
60*5/18*9 = 150 m.
1 hour = 3600 secs.
1 km = 1000 m.
3600/1000 = 36/10 = 5/18.
60*5/18*9 = 150 m.
