A train running at the speed of 80 km/h crosses a 350 m long tunnel in 36 seconds. The length of the train (in m) is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 450
Given,
The speed of the train = 80km/h = 80 × \(\frac{5}{18}\) = \(\frac{200}{9}\) m/sec
Time = 36 sec
Distance = 350 m
Let the length of the train = x meters.
We know that,
Speed = \(\frac{Distance}{Time}\)
\(\frac{200}{9}\) = \(\frac{x + 350}{36}\)
800 = x + 350
x = 800 - 350 = 450 meters
