Q1. Two trains, each having a speed of 38 km/h, are headed at each other on the identical straight track. A bird that can fly 70 km/h flies off the front of one train while they are 68 km apart and heads directly for the other train. On reaching 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?
