A train which 360m long takes 36 sec to cross a telegraph pole. How long will it take to cross a 600m long platform?

Speed of train in m/sec = 360m / 36 sec = 10 m/sec
Distance covered by train in crossing the platform = Length of train + Length of Platform = 360m + 240m = 600m
Therefore, Time taken to cover this distance = 600m /(10 m/sec)
= 60 sec
