Simplest way,
Our train took 9 secs at 60 kmph.
Convert the time taken into hours ->. 0025 hrs.
So, distance (required length) = Speed x Time = 60 x. 0025 =. 15 km = 150 m.

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

Convert km to m - 60000.
Convert hr to sec - 3600.
Sso, 60000/3600 = 16.666(speed) * 9 (time) = 150.
Convert hr to sec - 3600.
Sso, 60000/3600 = 16.666(speed) * 9 (time) = 150.
