Answer:
6 hrs taken by the man to reach station.
Step-by-step explanation:
Speed of man =6km/h
Speed of train=450/45 m/s=10m/s=10×3.6 km/hr= 36 km/h.
To convert m/s to km/h,multiply m/s by 3.6.
Therefore,station length=36 km.
Speed of train =36km/h,1 hour for 36 km taken by train.
For the man to go 36 km,
Speed of man =6km/h.
Therefore time taken by man to reach station=36/6 h=6h.
