Explanation:
Train 100m long and moving with velocity 60km/hr=60× 5/18 =>50/3 m/se
We have to find time train will take to cross a brige 1km i.e 1000m long.
Length of train be lt , length of bridge be lb and velocity of train be v
So time taken = (lt+lb)/v
= >(100+1000)/50/3
=>66sec
Hope this will help you
