Explanation:
Speed= 36*1000/60*60
10m/s
Total lenght to be covered

Time=distance /speed
990/10=99second

Total distance required for the train to cross the bridge is,
d = (100 + 880) m = 980 m
The speed of the train is,
v = 36 km/h = 36 × 5 / 18 = 10 m/s
Hence the time taken to cross the bridge is,
t = 980 / 10 = 98 s.
