Question

a train is 150 m long is running at 72kmph it cross a bridge in 13 second find the length and breadth of the bridge​

Answer 1

Answer:

so sorry.....I donno...........

Answer 2

Step-by-step explanation:

We can solve using this equation:

(length of bridge + length of train) = speed of train * time to cross bridge

So:

x + 150 = 72km/h * 13s

Convert 72km/h to m/s => 72000m/3600s => 20m/s (speed of train)

Now, solve:

x + 150m = 20m/s *13s => x + 150m = 260m => x = 260m - 150m => x = 110m (length of bridge)
