The Buzzkill Brain Teaser: A Collision Course

Prepare to be buzzed by this brain teaser! It’s a classic problem that challenges you to think outside the box and apply some basic math skills. Let’s see if you can solve the mystery of the buzzing bee and the colliding trains.

The Scenario

Imagine two trains, traveling on the same track, heading towards each other. One train is traveling at 60 miles per hour, and the other at 40 miles per hour. A bee is flying back and forth between the trains, starting on the front of the slower train. The bee flies at a constant speed of 80 miles per hour.

The trains are initially 100 miles apart. The question is: how far does the bee fly before the trains collide?

The Solution

This problem might seem tricky at first, but it’s actually quite straightforward with a little bit of logic. Here’s how to solve it:

  1. Calculate the combined speed of the trains: The trains are approaching each other, so their speeds add up. The combined speed is 60 mph + 40 mph = 100 mph.
  2. Calculate the time it takes for the trains to collide: Distance = Speed x Time. We know the distance (100 miles) and the combined speed (100 mph). Therefore, Time = Distance / Speed = 100 miles / 100 mph = 1 hour.
  3. Calculate the bee’s total distance: The bee flies for the entire duration of the trains’ journey, which is 1 hour. Distance = Speed x Time = 80 mph x 1 hour = 80 miles.

The Answer

The bee flies a total of 80 miles before the trains collide.

Why This Works

The key to solving this problem is realizing that the bee’s constant back-and-forth movement doesn’t affect the time it takes for the trains to collide. The bee’s flight time is the same as the time it takes for the trains to meet. Therefore, we only need to focus on the trains’ combined speed and the initial distance between them.
