Answer:
Step-by-step explanation:
we know that ..
distance
= time × speed
__________________________________________________________
speed of man
= 5km/h
= 5× 5/18 =25/18m/s
distance in 30 second
= 25/18×30=125/3=41.66 m
_________________________________________________________
so....
total distance
=41.66+ 274
=315.66 m
__________________________________________________________
speed of train
= distance / time
= 315.66/30
=10.52 m/s
__________________________________________________________
10.52m/s answer
