(The speed remains constant throughout the problem.) At time 0, a fast bee flies from one car towards the other. As soon as it reaches the other car, it turns around in infinitesimal time and heads back towards the first car. And so on. This bee flies at 30 miles per hour. How far does the bee travel before being demolished in the eventual collision? ...Ranjit
