The Bikes and The Bee

Two bikes are traveling toward each other at a constant speed of 10 mph. When the bikes are 20 miles apart, a bee flies from the front wheel of one of the bikes toward the other bike at a constant speed of 25 mph. As soon as it reaches the front wheel of the other bike, it immediately turns around and flies at 25 mph toward the first bike. It continues this pattern until the two bikes smush the bee between the two front tires.

How far did the bee travel?

25 miles.

The easiest way to think about this is to consider the time. The bikes will take 1 hour to touch, given that they start 20 miles apart and are each traveling toward each other at 10 mph.

Therefore the bee is buzzing back and forth at 25 mph for 1 hour.

I Am Two-faced, But Bear One Head

I am two-faced, but bear one head.
Men spill their blood for me.
I have no legs but travel widely.
I make kings immortal.
I am potent when shared,
Yet lust for my power keeps me locked away.

What am I?

Money (coins specifically). Coins have two faces, heads and tails. People fight for money, and money travels far and wide. Kings live on when they’re depticted on a coin. Sharing money with others is a meaningful experience yet many people keep their money locked up.

Archaeologist Laughed At

An archaeologist publicizes his find, a coin marked 649 BC, but is laughed at by his peers. Why?

No coins were ever marked BC because the BC / AD dating system wasn’t even devised until 525 AD. And it wasn’t widely used until after 800 AD.
