Sure, let's break this down step by step:

1. Initial Position Below Water Level:
The dolphin starts 1 meter below the water level. We can represent this position as -1 meter.

2. Final Position Above Water Level:
The dolphin then jumps to a position 3 meters above the water level. We can represent this position as +3 meters.

3. Calculate Distance Moved:
To find the total distance moved by the dolphin, we need to consider both the distance it moved from its initial position below the water level to the water level and from the water level to its final position above the water level.

- Distance from 1 meter below the water level to the water level: [tex]\(|-1|\)[/tex] = 1 meter
- Distance from the water level to 3 meters above the water level: [tex]\(+3\)[/tex] meters

4. Total Distance Moved:
The total distance the dolphin moved is the sum of these distances:
[tex]\(1 + 3 = 4\)[/tex] meters

Thus, the dolphin has moved a total of 4 meters.
