Question

two men are running along a railway track at the speed of 8kmph and 4kmph more in the same direction in which a train overtakes first man in 6¼ second and it take 2½ second more to overtake the second man than the first man. find the speed of the train kmph​

Answer 1

Answer:

Firstly we will assume the length of the train and speed of the train to be any variable. Then we will convert the speed of the persons into 

m/sm/s

. We will then form two equations based on the given condition and by using the distance, speed and time formula. Then by solving these two equations we will get the required value of the length of the train.
