No,, wrong Answer
okk
Yaaa
actually it's right
Total distance = 500 metres
Time taken = 30 seconds
Speed = distance / time
500 / 30 = 16.666 metres/second or 60 KMPH
Time taken = 30 seconds
Speed = distance / time
500 / 30 = 16.666 metres/second or 60 KMPH
500/30=50/3........my answer was correct
Ooo

Solution :-
Distance covered by the train = 400 m
Length of the train = 100 m
Total distance covered = 400 + 100 = 500 m
Time taken = 30 seconds
Speed = Distance/Time
= 500/30
= 50/3 m/sec
= 16.6667 m/sec
Speed in km/hr
Distance covered = 500 m or 0.5 km
Time taken - 30 seconds
= 30/(60*60)
= 30/3600
= 0.00833 hour
Speed = Distance/Time
= 0.5/0.00833
= 60.024 km/hr
Answer.
Distance covered by the train = 400 m
Length of the train = 100 m
Total distance covered = 400 + 100 = 500 m
Time taken = 30 seconds
Speed = Distance/Time
= 500/30
= 50/3 m/sec
= 16.6667 m/sec
Speed in km/hr
Distance covered = 500 m or 0.5 km
Time taken - 30 seconds
= 30/(60*60)
= 30/3600
= 0.00833 hour
Speed = Distance/Time
= 0.5/0.00833
= 60.024 km/hr
