Flying against the wind, an airplane travels 8370 kilometers in 9 hours. Flying with the wind, the same plane travels 9730 kilometers in 7 hours. What is the rate of the plane in still air and what is the rate of the wind?
Note that the ALEKS graphing calculator can be used to make computations easier.

Water flows at a steady rate from a tap. its takes 40 seconds to fill a 4 litre watering can from the tap. the rate at which water flows from the tap is halved. complete: 4 litres into cm3

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.
