in three, bird fli 78 zilyun trips bak & forth

In reel like, take it maebee 5 sekonds tu tern around

& distans be finite even with theritikal infinut round trips

2 kars go tuward eech other at 60 km/our & meet half wae tween 2 start spots=30 km

Eech kar go 30 km/our, so it take 1 our for the big krash

bird fli 1 our at 60 km/our, so mite make 60 km, sept for losses, tern-around time, time tu

get bak up tu kruiz

#### dif wae tu look at it...bird trip 1: kloes speed=30+60=90 km/our, dist=60, time=60/90

=0.6666666666... our

in that time 2 kars go tuward eech other (60 km/our)*(2/3)ours=40 km

trip 2...bird go 60 km/our tuward other kar, that kar go, so kloes speed=90 & dist=20 km

time2=20/90=2/9=0.2222222 ours

repeet this infinut times & yufind bird fli 1 our & go 60 km
