Hello Year 13 and welcome to your pages.
There will be more to come, but for now, think about this.....

The Fly and the Bicycles

Here is a classic problem. Little Darius and little Xerxes were 10 km apart. They rode their bicycles at a constant 10 km/hr toward each other. As they started off, a fly took off from one bicycle and flew to the other bicycle at 20 km/hr, then it flew back to the other bicycle, and then back and forth until it was crushed between the two bicycles when the two bicycles collided. Pretty stupid, all around. How far did the fly fly?
