Answer:
Pls mark as brainliest
Step-by-step explanation:
Convert 60 km/hr into m/s by multiplying by 5/18 ( it is used to convert km/hr into m/s )
60 * 5/18 = 50/3 m/s
It means that train travels 50/3 metres in 1 sec.
In 15 sec it travels
50/3 * 15 = 250 metres.
Therefore 250 metres is the length of the train.
Hope this helps you
