24. (Modeling) Space from the Spring of the Nile Large stream. [2 points]
The Nile Large stream in Africa is abquenched 4000 mi crave. The Nile begins as an quenchedlet of Lake Victoria at an elevation of 7000 ft over ocean roll and empties into the Mediterranean Ocean at ocean roll (0 ft). The space from its spring in thousands of miles is kindred to its elevation over ocean roll in thousands of feet (x) by the forthcoming countenance.

Restraint in, when the large stream is at an elevation of 600 ft, x = 0.6 (thousand), and the case from its spring is

, which portrays 3000 mi.

(Source: World Almanac and Book of Facts.)
