Thankyou byeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Answer 2

Answer:

Length of the train, Lt = 250m

Time, t= 30 sec

Speed of a person = 6kmph

Hence, S =D/T

As we know, the train and the man facing opposite to each other

Their speed will be added.

Speed of train + speed of the person = length of the train/time

Speed of train + 5/3 = (250/30)(18/5)

Speed of train =24kmph.
