Length of train = 90 m

Speed of train = 54 km/h

Speed of person = 6 km/h

Since the person is moving in the opposite direction, relative speed = 54 + 6 = 60 km/h

Convert into m/s:

6× 5/18 = 50/3 m/s

Time taken:

Time = Distance / Relative speed

= 90 ÷ (50/3)

= 90 × 3/50

= 5.4 seconds

So, the correct answer is 5.4 seconds
