For the two trains to meet, they must cover a total distance of 30 miles, since they are that far apart. Let x stand for the number of hours they travel.
Distance = Speed*Time
Total Distance = (Distance covered by the eastward train) + (Distance covered by the westward train)
30 = 70x + 50x
30 = 120x
x = 30/120 = 1/4 hour = 15 minutes.
