the train takes about 50/(48*5/18) sec to travel 50 m.
ie about 15/4 secs.
it crosses two poles in 15/4 secs.
therefor it will cross 2*60/(15/4) poles in 1 min
ie 32 poles
ans: 32 poles
How it could cross two poles in 15/4 sec. it ll cover 50 meters in this time. means only one pole u may cross if you consider that it starts from first pole then only first time u could say it crossed 2 poles second time when it ll cross third pole we have already counted second pole so only one is crossed in this 15/4 sec. and so on till end.
1-------2--------3--------
1 2 if we count in first 15/4 sec
then in next time slot only 3rd ll be counted how it could be 3 and 4.
