A train 180 m long takes 25 seconds to cross a platform 270 m long. What is the speed of the train (in m/s)?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 18
To cross a platform, a train covers its own length plus the length of the platform.
Distance covered \(=180+270=450\) m
Speed \(\displaystyle =\frac{450}{25}=18\) m/s
