Answer:
3.08 kmph
Step-by-step explanation:
The length of the platform is basically the distance
WKT: The length of the platform is double of it
therefore,
Distance: 200 + 200
= 400 m
Time : 36 secs
Speed = Dist/Time
= 400/36
= 11.1 m/s
In kmph
11.1 * 1000/ 3600
= 3.08 kmph
Hence, the speed of the train is 3.08 kmph
Hope you find it helpful :)
