The Hundred-Mile-An-Hour Dog

He was very happy when Trevor 's mother gave me cash and a dog while on vacation. Fast money! But the streaker is not an ordinary dog. She is a 4-legged rocket with weft thread! She should not walk - only the poor flight of the game, Trevor ends with her lead. So, when terrible Charlie Smugg bet Trevor, he could not train the Streaker at the end of the holiday, Trevor and his best friend Tina held the game in their hands. Can I find a way for Charlie to eat my own words using roller skating, cell phone, bicycle? Since this uncontrollable genius Jeremy is strong, this dream dog comedy has never relaxed its pace.

Boys, girls, dogs are in the same place straight. The boy and the girl walked in front - the boy walked 4 miles per hour and the girl walked 3 miles per hour. As they go, dogs come and go between them at a rate of ten miles per hour. We assume that the inversion of each direction is instantaneous. Where are the dogs after an hour? Almost everyone heard the old chest about birds. It flew back and forth between the two nearest locomotives. Let's assume that they are 30 miles apart, each traveling at 15 miles and birds fly back and forth at 60 miles as they get closer. How far did the birds fly before the two engines met? Alternatively, assuming that Achilles is chasing the turtle, the Trojan horses around and is hot, in order to achieve historical prospects.

The tsunami has hundreds of miles of wavelength and is much larger than the depth of the ocean. As a result, they move at shallow water wave velocity. It is hundreds of miles per hour and it is determined by the depth of the ocean. In seas far from the water, they are only a few feet tall and can not be detected by sensitive submarine instruments. As they arrive at the shore they slow down, grow in the highlands, break down like surfers and cross the lowlands. On the coast, the tsunami is small, it can not be detected, it will be several hundred meters high.

Whales and dolphins travel long distances, sometimes linearly swimming hundreds of miles, staying in a certain place for hours or days, moving a few miles along the coastline back to that road. These marine mammals can divide a few hundred meters and can stay in water for up to 30 minutes. They just spent 10-20% of the time on the ground. The sea is like a bird's air for whales and dolphins - a three dimensional environment in which they can move up, down, left and right. But whales and dolphins did not stop. Like seals and sea lions they have never been to the shore. Whales and dolphins are always swimming even if they are "asleep". They are 'voluntary breathers' and they realize every breath they take. They are constantly aware and are always moving. Knowing this, it is difficult to imagine that the tragedy of life is just a small swimming pool.
