Question 185319: two trains leave at the same time from stations that are 60Km apart. the train travel towards each other, one at 55 Km/h and the other at 65 Km/h. At the same time a bee flying at a constant rate of 80 Km/h starts at the front of one train, flies to the front of the other train, inmediately turns and flies back to the front of the first train, and so on.When the two trains meet, what is the total distance that the bee will have flown?

----------------------------
The trains approach each other at the sum of their speeds, 55+65, = 120 kph.
The stations are 60 km apart, so the trains meet after 1/2 hour, 60/120.
The bee flies at 80 kph for 1/2 hour, so it flies 40 kilometers.

It's a lot simpler than it first looks.
