I think we have to find the length of bridge...
total distance covered by train = 800m+x
x is the length of bridge
speed =60km/hr
Now it takes 120 sec to cross the bridge
120sec = 2min = 0.033 hr
Now, total distance = speed ×time = 60km/hr×0.033hr= 1.98km
Length of bridge=total distance-lenght of train= 1.98km-0.8km = 1.18km
total distance covered by train = 800m+x
x is the length of bridge
speed =60km/hr
Now it takes 120 sec to cross the bridge
120sec = 2min = 0.033 hr
Now, total distance = speed ×time = 60km/hr×0.033hr= 1.98km
Length of bridge=total distance-lenght of train= 1.98km-0.8km = 1.18km
