Length of train = 600m
Length of bridge = x m
Time to cross the bridge = 90 seconds.
Speed of train = 60 km/hr = 60*5/18 = 50/3 m/s
Total D = Length of train + Length of bridge
D = S * T
(600+x) = 90 * 50/3
600 + x = 1500
x = 1500-600 = 900 m or 0.9 km
Length of bridge is 900 m or 0.9 km
Hope it helps.
