A diver descends at a rate of 8 m/min. Which expression CANNOT be used to find her depth after 5 minutes?(1 point)

To find the diver's depth after 5 minutes while descending at a rate of 8 m/min, we need to use expressions that correctly represent the rate and the time. The depth can be calculated as follows:

1. **Total Depth = Rate × Time**: The diver descends 8 meters for each minute over 5 minutes, so the depth is calculated as:
- \(-8 \times 5\) (which gives -40 m, correctly representing the total depth).

2. **Adding Negative Depths**: Using repeated addition or subtraction to represent the depths:
- \(-8 + (-8) + (-8) + (-8) + (-8)\) (which simplifies to -40 m),
- \(-8 - 8 - 8 - 8 - 8\) (which also simplifies to -40 m).

Now, let's evaluate the final option:

- **\(-85\)** does not represent the correct calculation for the depth after 5 minutes, as this does not relate to multiplying the rate (8 m/min) by the time (5 min).

Thus, the expression **\(-85\)** cannot be used to find her depth after 5 minutes.
