Answer 1

Answer:

12 seconds

Step-by-step explanation:

Speed = Distance/Time

The train has to cross a 175m long bridge + Its own length to get the distance to be travelled to get the end of the train across the bridge.

Total distance = 175 + 125 = 300m

Converting km/h to m/s: 90/3.6 (formula to convert km/h to m/s: Speed/3.6)

                               = 25m/s

Therefore, time taken to cover 300m = 300/25 (Time= Distance/Speed)

                                         = 12 seconds

Hope this helps!
