Answer:
So total distance to be travelled =900m
Speed=36km/hr
= 36 × (5/18) m/s
= 10 m/s
Therefore
Time taken = distance/speed
= 900/10
= 90 sec

Answer:
Length to covered by train = bridge length + its own length
d=1000m+100m=1100m
train speed = 45 km/hr = 45×
3600hr
1000m
=12.5m/s
so, time taken =
v
d
=
(12.5)
1100
=88s
