distance = 100m+1000m
speed = 60km/hr = 60*5/18 = 300/8 m/s
time = 1100*8/300 = 88 sec
Total distance required for the train to cross the bridge is,
d = (100 + 1000) m = 1100 m
The speed of the train is,
v = 60 km/h = 60 × 5 / 18 = (50/3) m/s
Hence the time taken to cross the bridge is,
t = 1100 / (50/3) = 66 s.
