Final answer:
The difference in elevation between a city 5758 ft above sea level and a point 6 ft below sea level is 5764 ft.
Step-by-step explanation:
The student's question deals with calculating the difference in elevation between two points—one above sea level and one below sea level.
To find the difference in elevation, we add the absolute values of the two elevations since one is above and the other is below sea level. Thus, we have:
5758 ft (above sea level) + 6 ft (below sea level) = 5758 ft + 6 ft = 5764 ft.
This computation indicates that the difference in elevation between a city 5758 feet above sea level and a point 6 feet below sea level is 5764 feet.
