Answer:
Speed of the train is 50 km/hr or 125/9 m/s
Total distance the train will cover is Length of platform as well as its own length....
Thus the time taken = Distance / Speed...
= (120 + 130)/ ( 125/9)
= (250 ×9) / 125
= 18 seconds....
Hence the time taken is 18 seconds.....

Answer:
Total distance = 120m+130m=250m=0.25km
speed of train = distance/speed
so time = 0.25/50hours=1/200hours
Now 1 hour = 3600 seconds
Therefore,1/200hours = 3600/200=18 seconds
Thus,thus train will take 18 seconds to cross the platform.
