Answer:
The speed of the train is 25 km/hr.
Explanation:
Let the speed of the train be x. So with x speed, person one feels the speed as 3 km/hr and person two as 5 km/hr. So, the relative speed will be for person 1 (P1), it will be (x-3) km/hr and for person 2 (P2), it will be (x-5) km/hr.
Relative speed of 1st person = x-3
2nd on=x-4
x - 3*10 / 60 = x - 5*11 / 60
= 25
