Detailed Solution
Download Solution PDFGiven:
Speed of faster train = 29 km/hr
Speed of slower train = 25 km/hr
Time taken to cross a man in the slower train = 6 seconds
Formula used:
Relative speed when moving in opposite directions = Speed of faster train + Speed of slower train
Length of the faster train = Relative speed × Time
Calculation:
Relative speed = 29 km/hr + 25 km/hr
Relative speed = 54 km/hr
Convert speed to m/s: 54 km/hr = 54 × (1000/3600) m/s = 15 m/s
⇒ Length of the faster train = 15 m/s × 6 s
⇒ Length of the faster train = 90 m
∴ The correct answer is option (2).
