Car Talk Puzzler for the week of 11/23/13: Two trains are on a collision course. The trains are heading toward each other with identical speeds. When they are a certain distance apart from each other, a bee flies from the front of one train toward the other at constant speed. When it reaches the front of the other train, the bee turns around and flies back to the first train. The process repeats until the trains collide and the bee is squished.
The question: How far does the bee fly in the process?
To answer, you'll need the particulars: the distance between the trains when the bee begins its journey, the speed of the trains, and the speed of the bee. For these particulars (and the means by which you can enter your correct answer for the chance to win a prize), proceed to
The Car Talk Puzzler.

Puzzler submission auto-response:
Thanks for sending us your answer to this week's Car Talk puzzler!
In case you were wondering, here's the process we go through to select each week's winner:
First, we have to be certain you have the correct answer. We start by sending your answer to Paul Murky, at Murky Research. Murky, working with our Statistician Marge Innovera, will place your puzzler answer in one of two heaps: "not even close" and "pretty much right."
Assuming it passes by Paul and Marge, your answer will then be zipped along to Central Processing, where it will be date and time stamped, and searched for attached currency. Next, it will be shipped electronically to our Correct Answer Verification Center, where our legions of lackeys once again search your answer for any lingering currency -- just in case someone at Central Processing missed it. Then, they make certain that your response fits the criterion we have established for correct answers.
Please note that since we're often unsure of what the right answer is ourselves, we have very wide latitude in determining what constitutes a correct answer. Incorrect answers, however, will be sent to Nigerian Email Schemers.
Lastly, correct answers will be sent to Ms. Shirley Wright, who operates under the auspices of the Committee for Reviewing Answers to Puzzlers. There, operating under complete secrecy, Ms. Wright will pick a winner.
If your response is selected as this week's winning entry, we'll announce your name on the air. You'll also get a $26 gift certificate to our Shameless Commerce Division-- but only if you catch us. Which means, what? You'll need to e mail us and mention that you heard your name on the air. If you're smart, you'll then trade your new Shameless Commerce Gift Certificate to an unsuspecting co-worker, for a cup of coffee and twenty-five cents. Why $26? Simple. It used to be $25... but we adjusted for inflation. About ten years ago. (No kidding.)
Cordially,
