Question

A train 105m long is running at the speed of 54km/hr .how long will it take to cross a milestone?

Answer 1

Given speed of the train = 54km/hr
 
                                          = 54 * 5/18

                                          = 15 m/sec.

We know that Time = distance/speed.

                                  = 105/15

                                  = 7 seconds.


It will take 7 seconds to cross a milestone.
