Respuesta :
The greatest amount of change in Alexandra's depth while scuba diving over a single 5-minute period would be the 15th to 20th-minute period, where she was able to go from -22.98M to -6.6M covering a 16.38M run.
Answer: After 15 minutes she reached -22.98 meters best represent the the greatest amount of change in her depth over a single 5-minute period.
Step-by-step explanation:
Given: Alexandra checks her instruments and makes note of her depth in every 5 minutes.
From the given depth readings from her first 20 minutes of diving we can see the greatest amount of change in her depth over a single 5-minute period is -22.98 meters.
Hence, after 15 minutes she reached -22.98 meters best represent the the greatest amount of change in her depth over a single 5-minute period.
