An airplane flies against the wind from A to B in 8 hours. The same airplane returns from B to A, in the same direction as the wind, in 7 hours. Find the ratio of the speed of the airplane (in still air) to the speed of the wind.
Let x = speed of airplane in still air, y = speed of wind and D the distance between A and B. Find the ratio x / y Against the wind: D = 8(x - y), with the wind: D = 7(x + y) 8x - 8y = 7x + 7y, hence x / y = 15

"What does the Bible say about dinosaurs? Are there dinosaurs in the Bible?"
The topic of dinosaurs in the Bible is part of a larger ongoing debate within the Christian community over the age of the earth, the proper interpretation of Genesis, and how to interpret the physical evidences we find all around us. Those who believe in an older age for the earth tend to agree that the Bible does not mention dinosaurs, because, according to their paradigm, dinosaurs died out millions of years before the first man ever walked the earth. The men who wrote the Bible could not have seen living dinosaurs.
