They will travel a total of 1300 miles when they meet, since they will meet at some point in the middle.
So 1300 = 125[T] + 135[T], with T being the amount of time in hours.
Thus 1300 = 260T, or T = 5. They meet in 5 hours.
[Sorry for the original addition error.]

Wide Awake set the question up correctly, but made one small mistake:
The trains travel 1300 km, so:
1300 km = 125t + 135t
1300 km = 260t (not 160t)
5 h = t (soluton)
