Speed =distance/time
V=100/5
V=20m/s
T=distance/speed
Total distance =100+500=600
T=600/20
=30s
V=100/5
V=20m/s
T=distance/speed
Total distance =100+500=600
T=600/20
=30s

Speed of train is,
v = 100 / 5 = 20 m/s
Total distance required for the train to cross the bridge is,
d = (100 + 500) m = 600 m
Hence the time taken to cross the bridge is,
t = 600 / 20 = 30 s.
