Final answer:
The diver's average change in elevation per minute is 3.2 feet, calculated by dividing the total change in elevation by the total time spent diving.
Step-by-step explanation:
The question asks to calculate the diver's average change in elevation per minute. To find this, we can use the formula for average rate of change, which is:
Average Change per Minute = Total Change in Elevation ÷ Total Time
Plugging in the provided numbers:
Average Change per Minute = 17.28 feet ÷ 5.4 minutes = 3.2 feet per minute (rounded to two decimal places).
Therefore, the diver's average change in elevation per minute is 3.2 feet.
