wo trains, each having a speed of 30 km/h, are headed at each other on the same straight track. A bird that can fly 60 km/h files off the front of one train when they are 60 km apart and heads directly for the other tain. On rreaching the other train it files directly back to the first train, and so forth. (a) how many trips can the bird make from one train to the other before they crash?

V train 1 = Vtrain2 = 8.33 m/s (after changing km.hr)
time, t = 30000/8.33 = 3600 s.
16.667 = distance/3600
distance = 60000 m
