The Three Wise Owls (at the posted coordinates)

Three old and clever owls are guarding this cache. In order to find this cache you must show that you are a worthy cacher and solve their mysterious puzzles. If you fail to answer their question, they will use their mistrious power and will drain all your Geocaching mojo. But wait before you begin you quest thw owls decided that the first three wise cachers that will succeed in this difficult task will get an extra bonus they can give one of the owls their cacher names. So are you brave enough to begin the quest ?

The Question of Owl A- Dogmael:

Two Kings decide to Meet; so they start riding horses towards each other. Since they are proud (so they cannot meet at the other king castle) they plan to meet halfway. Each is riding at 6 MPH. There castles are 36 miles apart. One of them has a pet carrier falcon and it starts flying the instant the kings start traveling. The falcon flies back and forth at 18 MPH between the 2 kings until the kings meet.

How many hours will it take then to meet (Let the answer be A) and how many miles does the falcon travel (Let the answer be BC)?

The Question of Owl B - LeGrandChrist :

Five pirates have obtained 100 gold coins and have to divide up the loot. The pirates are all extremely intelligent, treacherous and selfish (especially the captain).

The captain always proposes a distribution of the loot. All pirates vote on the proposal, and if half the crew or more go "Aye", the loot is divided as proposed, as no pirate would be willing to take on the captain without superior force on their side.

If the captain fails to obtain support of at least half his crew (which includes himself), he faces a mutiny, and all pirates will turn against him and make him walk the plank. The pirates start over again with the next senior pirate as captain.

What is the maximum number of coins the captain can keep without risking his life?

Let the answer be (DE)

The last Question by Owl C - Jeehell:

Ten people land on a deserted island. There they find lots of coconuts and a monkey. During their first day they gather coconuts and put them all in a community pile. After working all day they decide to sleep and divide them into ten equal piles the next morning.

That night one castaway wakes up hungry and decides to take his share early. After dividing up the coconuts he finds he is one coconut short of ten equal piles. He also notices the monkey holding one more coconut. So he tries to take the monkey's coconut to have a total evenly divisible by 10. However when he tries to take it the monkey conks him on the head with it and kills him.

Later another castaway wakes up hungry and decides to take his share early. On the way to the coconuts he finds the body of the first castaway, which pleases him because he will now be entitled to 1/9 of the total pile. After dividing them up into nine piles he is again one coconut short and tries to take the monkey's slightly bloodied coconut. The monkey conks the second man on the head and kills him.

One by one each of the remaining castaways goes through the same process, until the 10th person to wake up gets the entire pile for himself. What is the smallest number of possible coconuts in the pile, not counting the monkeys?

Let the answer be FGHI

Cache Sum A+B+C+D+E+F+G+H+I = 46

Since you all are talented cacher I can assume you bravely passed the three owls challenges so I will leave you with one last riddle to ponder while you go get your treasure:

One day three Greek philosophers settled under the shade of an olive tree, opened a bottle of Retsina, and began a lengthy discussion of the Fundamental Ontological Question: Why does anything exist?

After a while, they began to ramble. Then, one by one, they fell asleep.

While the men slept, three owls, one above each philosopher, completed their digestive process, dropped a present on each philosopher's forehead, the flew off with a noisy "hoot."

Perhaps the hoot awakened the philosophers. As soon as they looked at each other, all three began, simultaneously, to laugh. Then, one of them abruptly stopped laughing. Why?
