To analyze the rate of decline in height above the canyon floor over time based on the provided data, we can calculate the change in height for the given time intervals.

  1. From 0 to 3 minutes: The height decreases from 360 to 280.

    • Change in height = 280 - 360 = -80
    • Change in time = 3 - 0 = 3 minutes
    • Rate of change = -80 / 3 ≈ -26.67 feet per minute
  2. From 3 to 10 minutes: The height decreases from 280 to 160.

    • Change in height = 160 - 280 = -120
    • Change in time = 10 - 3 = 7 minutes
    • Rate of change = -120 / 7 ≈ -17.14 feet per minute
  3. From 10 to 14 minutes: The height decreases from 160 to 80.

    • Change in height = 80 - 160 = -80
    • Change in time = 14 - 10 = 4 minutes
    • Rate of change = -80 / 4 = -20 feet per minute

Now, we summarize the rate of change over the entire period:

  • The average rate of change over the entire time, from 0 to 14 minutes, involves calculating the total change in height and total time:
    • Total change in height = 80 - 360 = -280
    • Total time = 14 - 0 = 14 minutes
    • Average rate of change = -280 / 14 = -20 feet per minute

Based on this analysis, we can interpret the rate of change of height above the canyon floor over time.

Interpretation: The height above the canyon floor decreases at an average rate of approximately 20 feet per minute. This indicates a consistent decline in height as time progresses, suggesting a linear relationship between height and time.
