To find the average rate of change for the diver’s depth, we can use the formula for average rate of change:

\[
\text{Average Rate of Change} = \frac{\text{Change in Depth}}{\text{Change in Time}}
\]

1. **Determine the change in depth**:
- The diver starts at a depth of 15 meters and descends to a depth that is 10 meters lower.
- So, the final depth is \( 15 + 10 = 25 \) meters.
- The change in depth is:
\[
\text{Change in Depth} = \text{Final Depth} - \text{Initial Depth} = 25 - 15 = 10 \text{ meters}
\]

2. **Determine the change in time**:
- The dive took 10.1 seconds.

3. **Calculate the average rate of change**:
\[
\text{Average Rate of Change} = \frac{10 \text{ meters}}{10.1 \text{ seconds}} \approx 0.9901 \text{ meters/second}
\]

Rounding to the nearest hundredth, this value is approximately \(0.99\) meters/second. Since the diver is descending, we can also express this as negative, so it would be:

- The quotient that describes the average rate of change for the diver’s depth is \(-0.99\) meters/second.

Thus, you should choose the option:

**The quotient that describes the average rate of change for the diver’s depth is −0.99 meters/second.**
