What was the diver's average change in elevation per minute?
A. The diver descended 476.67 feet per minute.
B. The diver descended 3.8 feet per minute.
C. The diver descended 0.26 feet per minute.
The average change in elevation per minute can be calculated by dividing the total change in elevation (550 feet) by the total time (2 minutes).
Average change in elevation per minute = Total change in elevation / Total time
= 550 feet / 2 minutes
= 275 feet per minute
Therefore, the correct answer is not provided in the options given.
