My daughter has a homework problem and I dont even know where to start!! Here it is

Two trains are 150 km apart and are heading toward each other on a single track. The first train is going 90 km an hour. The second train is going 60 km an hour.
Flying at a constant speed of 110 km an hour, a bird takes off from the head of the first train flies to the head of the second train, turns and flies back to the head of the first train. The bird keeps going like this till until the two trains crash.
How far does the bird fly?

How long would it take for the trains to crash into each other?
 
Ok...how many km's does the bird fly during that 1 hour? :idea:
