Question
Kavi Guru Express moving at 50 km/hr crosses the Ajay River Bridge in 45 seconds. The length of Kavi Guru Express is 150 meters. Find the length of the Ajay River Bridge?
The distance covered by train when it crosses the bridge is equal to the sum of the length of the train and length of the bridge.
Speed of train in m/s = 50*(5/18) = 250/18 m/s
Time = 40 seconds
Let the length of the bridge is X.
(length of the bridge+length of the train)/(time taken to cross the bridge)= speed of train
(X+150)/45 = 125/9 = speed of train
9(X+150) = 45x125
9X+450= 5625
9X= 5625 - 450
9X=5175
X=5715/9 = 635
