To determine the average rate of change in the diver's depth, we need to calculate the change in depth and divide it by the time taken for that change.
1. **Initial depth**: 15 meters below the surface (this is -15 meters).
2. **Final depth**: 10 meters lower than her initial depth means she descends to a depth of 25 meters below the surface (which is -25 meters).
3. **Change in depth**:
\[
\text{Change in depth} = \text{Final depth} - \text{Initial depth} = -25 - (-15) = -25 + 15 = -10 \text{ meters}
\]
4. **Time taken**: 10.1 seconds.
5. **Average rate of change**:
\[
\text{Average rate of change} = \frac{\text{Change in depth}}{\text{Time}} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.9901 \text{ meters/second}
\]
Rounding to the nearest hundredth, we find that the average rate of change for the diver's depth is approximately **−0.99 meters/second**.
Thus, the response is:
**The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.**
1. **Initial depth**: 15 meters below the surface (this is -15 meters).
2. **Final depth**: 10 meters lower than her initial depth means she descends to a depth of 25 meters below the surface (which is -25 meters).
3. **Change in depth**:
\[
\text{Change in depth} = \text{Final depth} - \text{Initial depth} = -25 - (-15) = -25 + 15 = -10 \text{ meters}
\]
4. **Time taken**: 10.1 seconds.
5. **Average rate of change**:
\[
\text{Average rate of change} = \frac{\text{Change in depth}}{\text{Time}} = \frac{-10 \text{ meters}}{10.1 \text{ seconds}} \approx -0.9901 \text{ meters/second}
\]
Rounding to the nearest hundredth, we find that the average rate of change for the diver's depth is approximately **−0.99 meters/second**.
Thus, the response is:
**The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.**
