Given:

Speed of train1 = 48 km/h

Speed of train2 = 60 km/h

Time taken to cross a man = 12 sec

Formula used:

Speed = Distance / Time

Calculation:

As the train is moving in the opposite direction,

⇒ Relative speed = Speed of train1 + speed of train2 = 48 + 60 = 108 km/h = 30 m/s

The length of train is the distance he travelled to cross the train

⇒ Speed = Distance / Time

⇒ 30 = Distance / 12

⇒ Distance = 30 × 12 = 360 m

⇒ Hence, Length of the slower train is 360 m
