To find the average rate of change of the diver's depth, we need to determine the change in depth and divide it by the time taken for that change.
1. **Initial depth**: The diver starts at 15 meters below the surface, which we can represent as -15 meters.
2. **Final depth**: The diver descends to a depth that is 10 meters lower than her starting depth:
\[
\text{Final depth} = -15 \, \text{meters} - 10 \, \text{meters} = -25 \, \text{meters}
\]
3. **Change in depth**:
\[
\text{Change in depth} = \text{Final depth} - \text{Initial depth} = -25 \, \text{meters} - (-15 \, \text{meters}) = -25 + 15 = -10 \, \text{meters}
\]
4. **Time taken**: The diver took 10.1 seconds to make this descent.
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 this to the nearest hundredth, we get:
\[
-0.99 \, \text{meters/second}
\]
The correct response is:
**The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.**
1. **Initial depth**: The diver starts at 15 meters below the surface, which we can represent as -15 meters.
2. **Final depth**: The diver descends to a depth that is 10 meters lower than her starting depth:
\[
\text{Final depth} = -15 \, \text{meters} - 10 \, \text{meters} = -25 \, \text{meters}
\]
3. **Change in depth**:
\[
\text{Change in depth} = \text{Final depth} - \text{Initial depth} = -25 \, \text{meters} - (-15 \, \text{meters}) = -25 + 15 = -10 \, \text{meters}
\]
4. **Time taken**: The diver took 10.1 seconds to make this descent.
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 this to the nearest hundredth, we get:
\[
-0.99 \, \text{meters/second}
\]
The correct response is:
**The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.**
