50 m is the distance between 2 poles...so speed of sampark kranti is approx 95kmph!!
as per i know crossing 25/26 poles means 1 km....rest u can calculate
we may not calculate speed accurately due to eye paralax error.
we can never calculate anything exactly.we always calaulete things with some approximity or level of accuracy.
Here , speed calculated should not vary much because the error in noticing time is even less than 1 sec. for a normal eye...so accuracy is quite acceptable..
