A train 150 m long passes a platform 550 m long in 56 seconds. How much time will the same train take to pass a platform 250 m long?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 32 seconds
To pass a platform the train covers its own length plus the platform's length. The first platform gives the speed; the speed is the same for the second.
Distance for the first platform \(=150+550=700\) m
Speed \(\displaystyle =\frac{700}{56}=12.5\) m/s
Distance for the second platform \(=150+250=400\) m
Time \(\displaystyle =\frac{400}{12.5}=32\) seconds
