Question 896817: Two bicyclists travel toward each other, each traveling at a uniform speed of 5 km/h. At the moment that they are 30 km apart, a bumblebee flies from the front wheel of one of the bikes at a uniform speed of 11 km/h directly to the wheel of the other bike. It touches it and turns around and returns at the same speed to the first bike, whereupon it touches the wheel and instantaneously turns around and repeats the back-and-forth trip over and over again--trips becoming shorter and shorter until the bikes collide and squash the unfortunate bee between the front wheels. How far does the bee travel?

Two bicyclists travel toward each other, each traveling at a uniform speed of 5 km/h. At the moment that they are 30 km apart, a bumblebee flies from the front wheel of one of the bikes at a uniform speed of 11 km/h directly to the wheel of the other bike. It touches it and turns around and returns at the same speed to the first bike, whereupon it touches the wheel and instantaneously turns around and repeats the back-and-forth trip over and over again--trips becoming shorter and shorter until the bikes collide and squash the unfortunate bee between the front wheels. How far does the bee travel?
---------------
Going in opposite directions, the speeds are added --> 10 km/hr
d = r*t
t = d/r = 30/10 = 3 hours until they meet.
---
The bee flies at 11 km/hr for 3 hours.
