Total distance the bird travels before the trains collide

Q1. Two trains, each having a speed of 20km/h, are headed at each other on the same straight track. A bird that can fly 60km/h flies off the front of one train, when they are 52 km apart and heads directly for the other train. On reaching the other train it flies directly back to the first train, and so forth. (We have no idea why a bird would behave in this way.) What is the total distance the bird travels before the trains collide?

Q2. In a bicycle race, the leader is travelling with a constant velocity of 11.10 m/s and is 10.0 m ahead of the second-place cyclist. The second place cyclist has a velocity of 9.50 m/s and an acceleration of 1.20 m/s squared. How much time elapses before second place cyclist catches the leader?
