Answer 1

Answer:

16.38 meters represents the greatest amount of change in her depth over a single 5-minute period

Step-by-step explanation:

From time = 0 to time = 5 the amount of change in her depth was -12.45 - 0 = -12.45 meters

From time = 5 to time = 10 the amount of change in her depth was -9.7 - (-12.45) = -2.75 meters

From time = 10 to time = 15 the amount of change in her depth was -22.98 - (-9.7) = -13.28 meters

From time = 15 to time = 20 the amount of change in her depth was -6.6 -  (-22.98) = 16.38 meters
