Best to draw a timeline with a diagram for each key moment in time. Let us know if you get stuck.

How long before the trains meet? How long is the bird in the air? How far can the bird fly in that time?

60 km

The bird is traveling for an hour because it takes the two trains 60 minutes to travel 30 km to the point of collision. Since the bird has been flying for 60 minutes and it traveles 1 km per minute, (60 min) * (1 km / min) = 60 km
