A scuba diver dove from the surface of the ocean to an elevation of −69 9/10 feet at a rate of −14 feet per minute. After spending 14 minutes at that elevation, the diver ascended to an elevation of −18 9/10 feet. The total time for the dive so far was 21 1 8 minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.

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.
