simple !!!

length of the platform + length of train => 200+ 250 => 450m


speed => 5/18 × 36

=> 10m/ s


so total time => total distance / speed


so time is

=> 450/ 10

=>10s


hope it help you !!

thanks !!

Hey!!!
Explanation:
Speed= (36×5/18)m/s
=10m/s
Length= length of train + length of platform
= 250+200m
=450m
so as we know,
distance(length of train) = speed×time
time = distance(length of train)/speed
= 450/10
=45 second ans
