Starting at the equator, a bird flies a constant direction: northwest (his path will always intersect the merideans at 45 degrees). He is a fast bird, flying 200 kilometers an hour.
The earth's radius is about 6050 kilometers, it's circumference about 38025 kilometers.
How long will it take the bird to reach the north pole?
