Speed = Distance /Time
Train travels Distance D = 50*(t+10/60) Km -----eq1 {t = regular time}
Train travel Same Distance D = 30*(t+50/60)Km ----eq2
Solving Eq1 EQ2
50*(t+10/60) = 30*(t+50/60)
We get t = 50 min or 50/60 Hrs
So Putting the value in eq1
we get D = 50 Km
Thus, Distance B|w Station A and B is 50 Km.
