We shall use a negative sign for an elevation below sea level, and a positive sign for an elevation above sea level.
Given:
Elevation of city A = -96 ft (below sea level)
Elevation of city C = -24 ft (below sea level)
Let x = elevation of city D.
Part A.
Because the elevation of city D is 1/4 of the elevation of city C, therefore
x = (1/4)*(-24)
Part B.
Because 24/4 = 6, therefore
x = -6 ft.
Answer:
The elevation of city D is 6 feet below sea level.
The answer is negative because the elevation is below sea level.
Answer:
