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
