Question

How long will a 150 m long train running at a speed of 60 kmph take to cross a bridge of 300 m?

Answer 1

Answer:

The Train will enter and then leave, that means it needs to Cover a distance of total (300+150) = 450 m or 0.45 KM.

Time taken to travel = Distance / Speed

0.45/60 = 0.0075Hr    

or  

0.0075 * 60 = 0.45 Minute  

or

0.45*60 = 27 seconds
