Losing Ten Minutes An Hour

A clock loses exactly ten minutes every hour. If the clock is set correctly at noon, what is the correct time when the clock reads 3:00pm?

3:36pm. For every 60 minutes of real time, the clock moves 50 minutes. Put another way, 60/50 = 1.2 real minutes per slow-clock minute.

In order for the clock to show 3:00pm, 180 of its slow minutes have to pass. 1.2 * 180 clock minutes = 216 real minutes or 3 hours and 36 minutes.

Favorite Pet is a Fish

I died and came back to life. My blood is not easily able to go through my body. My favorite pet is a fish. Who am I?

A shark. Sharks experience tonic immobility, also known as apparent death, where they appear to have died. Blood does not easily flow through their bodies, forcing sharks to swim continuously to circulate their blood. Lastly, sharks have pet fish called Remora (sometimes called suckerfish). They feed on parasites on the sharks and leftovers, and they use the shark as transport and protection.

A big thanks to Saravana for answering this.

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.

I Can Be Quick, And Then I’m Deadly

I can be quick and then I’m deadly,
I am a rock, shell and bone medley.
If I was made into a man, I’d make people dream,
I gather in millions by ocean, sea and stream.

Sand. Quicksand is deadly (at least in movies). Sand is made up of rocks, shells and bones. The sandman visits you when you dream (again, according to legend, I’ve never seen him…) and there is plenty of sand in the oceans, seas and streams.

First One, Then I Seem None

First I am one, then I seem none,
In death I birth new life.
What’s raised exceeds me,
For on bent knee,
I add to a world that’s rife.

What am I?

A seed. One seed turns into a plant or tree and seemingly disappears. When a plant dies, the seeds can be harvested to create new plants. From a single seed, hundreds more are created, vastly exceeding the original. Gardeners care for plants on bent knee and each new plant helps make the air fresher.

Petals Around the Rose

Here are five rolls of dice, with their score.

Roll #1 – Score: 6

Roll #2 – Score: 4

Roll #3 – Score: 4

Roll #4 – Score: 8

Roll #5: 0

This is what you know:

1. The name of this game is significant (Petals Around the Rose)
2. The answer is always even

How is the score determined?

The solution is to count the dots (petals) surrounding the center dot (the rose).

Only odd numbers have a center dot, so even numbers (2, 4 and 6) are worth zero.

1 doesn’t have any surrounding dots, so it too is worth zero.

The three has two dots surrounding the center, so it’s worth two.

A five has four petals around the rose making it worth four.
