To solve the problem, we need to determine how long it will take for the fish to descend from its current depth of -10.8 meters to a depth of -37.8 meters.
1. **Calculate the total depth change required:**
Current depth = -10.8 meters
Desired depth = -37.8 meters
Total depth change = Desired depth - Current depth
\[
\text{Total depth change} = -37.8 - (-10.8) = -37.8 + 10.8 = -27.0 \text{ meters}
\]
The fish needs to descend 27.0 meters.
2. **Determine the rate of descent:**
The fish descends 1.5 meters every 2 minutes.
3. **Calculate how many descents are needed to reach the total depth change:**
To find out how many 1.5 meter descents are needed to reach a total of 27.0 meters, divide the total depth change by the depth per descent:
\[
\text{Number of descents} = \frac{27.0 \text{ meters}}{1.5 \text{ meters per descent}} = 18
\]
4. **Calculate the total time taken for these descents:**
Since each descent takes 2 minutes, we multiply the number of descents by the time per descent:
\[
\text{Total time} = 18 \text{ descents} \times 2 \text{ minutes per descent} = 36 \text{ minutes}
\]
**Conclusion:**
It will take the fish 36 minutes to reach a depth of -37.8 meters. This means that after 36 minutes of continuous swimming downwards at the rate of 1.5 meters every 2 minutes, the fish will be at a depth of 37.8 meters below sea level.
1. **Calculate the total depth change required:**
Current depth = -10.8 meters
Desired depth = -37.8 meters
Total depth change = Desired depth - Current depth
\[
\text{Total depth change} = -37.8 - (-10.8) = -37.8 + 10.8 = -27.0 \text{ meters}
\]
The fish needs to descend 27.0 meters.
2. **Determine the rate of descent:**
The fish descends 1.5 meters every 2 minutes.
3. **Calculate how many descents are needed to reach the total depth change:**
To find out how many 1.5 meter descents are needed to reach a total of 27.0 meters, divide the total depth change by the depth per descent:
\[
\text{Number of descents} = \frac{27.0 \text{ meters}}{1.5 \text{ meters per descent}} = 18
\]
4. **Calculate the total time taken for these descents:**
Since each descent takes 2 minutes, we multiply the number of descents by the time per descent:
\[
\text{Total time} = 18 \text{ descents} \times 2 \text{ minutes per descent} = 36 \text{ minutes}

**Conclusion:**
It will take the fish 36 minutes to reach a depth of -37.8 meters. This means that after 36 minutes of continuous swimming downwards at the rate of 1.5 meters every 2 minutes, the fish will be at a depth of 37.8 meters below sea level.
