Question

A train 280m.long is moving at a speed of 60 kmph.what is the time taken by the train to cross a bridge320m.long?

Answer 1

Given that speed of the train = 60kmph

                                                  = 60 * 5/18

                                                  = 50/3 m/s.


Given that length of train = 280m.

Given that length of the bridge = 320m.

Total distance = 280 + 320

                        = 600.


We know that Time = Distance/Speed

                                 = 600/50/3

                                 = 600 * 3/50

                                 = 36 sec.


Hope this helps!
