ost_uid0="blanka09"]Gee.. I wonder why it took such a long time to ask :biggrin:
Ok now let me give you the additional clue and... hmm.. let me see
I'll alter some numbers here..
Let's say the whole scenario is the same and the trains are moving at each other at half of the speed said earlier,
They are 60km apart when this strange bird starts it's trajectory
and as the smart one asked.. the bird is flying 60km/h
Now beat that :biggrin:[/quote]
At Each other at half the Speed....
Or away from Each other at half the Speed....
...Wait your changing the numbers so...is the Birds orignal speed of flight 120km..... (0_o)
