Question

. A train, 177 m long, crosses a platform, 273 m long, in 27 seconds.
What is the speed of the train in km/h?​

Answer 1

Answer:

When the speed of running train or vehicle is measured it is usually from a single static point. However, here the static point is not single but the whole platform. We have a train which is 177 m long and a platform which is also 273 m long and the time taken for the whole train to cross the platform is 27 s.

Answer 2

Answer:

total distance travelled by the train= length of platform- length of train

                                                           273m-177m

                                                             96m

time=27s

speed = distance/time

             96m/27s

              3.56m/s

in km/h=3.56*5/18

            0.99km/h

hope this answer is correct
