Question
How much time a train 200 metres long running at the
speed of 72 km/hr take to cross a bridge 180 metres in length?    ÂSolution
Distance (Length of the train + length of the bridge) = 200 + 180 = 380 Speed of Train = 72 km/hr = 72×5/18  = 20 m/sec.  Time = Distance/Speed  = 380/20  = 19 sec.
