Final answer:
The diver's total change in elevation is 80 feet, and as this total change is divided into 4 equal intervals, the change in elevation in each interval is 20 feet.
The correct option is not given.
Step-by-step explanation:
The student's question pertains to the change in elevation a diver experiences while descending below sea level in equal intervals. To find the diver's change in elevation per interval, we first need to determine the total change in elevation. The diver starts at 14 feet below sea level and goes down to 94 feet below sea level. Therefore, the total change is the final elevation minus the initial elevation.
Total change in elevation = Final elevation - Initial elevation
= 94 feet below sea level - 14 feet below sea level
= 80 feet
Since the diver descends in 4 equal intervals, we divide the total change by the number of intervals:
Change in elevation per interval = Total change in elevation / Number of intervals
= 80 feet / 4
= 20 feet
Therefore, the diver's change in elevation in each interval is 20 feet.
