A train of length 180 meters is running at a speed of 72 km/h. How much time will it take to cross a bridge 350 meters long?
26.5 seconds
To cross a bridge, the train must cover a distance equal to its own length plus the bridge length.
Total distance: \(180 + 350 = 530\) meters.
Convert the speed from km/h to m/s: \(72 \times \frac{5}{18} = 20\) m s-1.
Time equals distance divided by speed: \(t = \frac{530}{20} = 26.5\) seconds.
Hence, the train takes 26.5 seconds to cross the bridge.
