Final answer:
The elevation difference between Sam's location on Dacula Mountain and Kendall's location in Florida valley is 152 meters, calculated by subtracting Kendall's elevation from Sam's elevation.
Step-by-step explanation:
The difference in elevation between where Sam and Kendall are standing can be found by subtracting the elevation of the lower point from the elevation of the higher point. Sam is at an elevation of 156 meters above sea level while Kendall is at an elevation of 4 meters above sea level. Therefore, the difference in their elevation is:
156 meters (Sam's elevation) - 4 meters (Kendall's elevation) = 152 meters
The correct answer is A. 152 meters.
