Question

A man is walking at a speed of 6 km/hr by the side of a rail track. A 450 m long train moving in the same direction crosses him in 45 seconds, and reaches next stations after 1 hour of crossing. Then find after how much time the man will reach at the same station?

Answer 1

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.
