Train is of length 1km and tunnel of 1km.
As the forward part of the train enters and then leave the tunnel ,the back most part of the train enters
Therefore total distance = 2km
Speed = distance /time
Time = 2 /60
= 1/30 hrs
=2mins

Answer:
train's length is 1 km= 1000 m
and tunnel length is 1000 m
so 1000+1000=2000
speed is 60km/h or 3600m/h
so, 2000/3600*18/5= 20/36*18/5= 4/2=2 minutes
so train will take 2minites.
