Question

a train 400 m long is running at the speed of 36 km per hour what time it will be take to cross 150 metre long Bridge​

Answer 1

55 seconds to cross a 150 m long bridge.

Step-by-step explanation:

The length of train = 400 m

length of bridge = 150 m

Total distance to cover by train = 150+400 = 550 m

Speed of train = 36 km/h

$time=\dfrac{distance}{speed}$

$time=\dfrac{550}{36}\dfrac{1}{1000}\times 3600$  

$\because 1\ h=3600\ sec$

$\because 1\ km=1000\ m$

time = 55 seconds
