Atrain moves south with a speed of 20 m/s. a man on the train walks south with a speed of 0.2 m/s relative to the train. how long does it take the man to move 8 m relative to the train? a. 15 s b. 32 s c. 40 s d. 0.41 s

Time, t = 40 seconds

Explanation:

It is given that,

Speed of the train, v = 20 m/s

Speed of a man with respect to train, v' = 0.2 m/s

Let t is the time taken by the man to move 8 meters relative to the train. It can be calculated as :

t = 40 s

So, the time taken by the man to move 8 m relative to the train is 40 seconds. Hence, this is the required solution.
