340 மீ நீளமுள்ள ரயில் மணிக்கு 40கி.மீ வேகத்தில் சென்றால் 150 மீ நீளமுள்ள பாலத்தை கடக்க எவ்வளவு நேரம் ஆகும்? If a 340 m long train travels at 40 km / h, how long will it take to cross the 150 m long bridge?

The total distance the train must cover to cross the bridge is the sum of its length and the bridge's length, which is 340 + 150 = 490 meters. The speed of the train is 40 km/h, which we convert to meters per second by multiplying by 5/18, giving 100/9 m/s. Using the formula time = distance / speed, we get 490 / (100/9) = 44.1 seconds. It will take 44.1 seconds to cross the bridge.
