-------------
Closing speed for the two trains is 48+54 = 102 km/hr
---
After 12 hrs they had covered 12*102 = 1224 km
---
They were 1822-1224 = 598 apart

..
Train A 48 km /h distance traveled in 12 hours = x km
Distance = speed * time
it has traveled 576 km
Train B 54 km/h distance traveled in 12 hours =
Train B has traveled 12*54 km= 648 km
Distance apart = 1822 - (576+648)
= 598 km
