A plane flying to Honolulu, Hawaii with a tailwind averaged 190 km/h. On the return trip back to Kansas City, it only averaged 122 km/h while flying back into the same wind. What is the speed of the wind and what is the speed of the plane in still air? Make sure to list what x and y is and your equations.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
