Answer:
7.65 meters.
Step-by-step explanation:
Let x represent the distance that diver will travel.
We have been given that a scuba diver is exploring at an elevation of -12.2 meters. As the diver rises to the surface, she plans to stop and rest briefly at a reef that has an elevation of -4.55 meters. We are asked to find the distance that diver will travel.
The initial elevation plus x will be equal to -4.55 meters. We can represent our given information in an equation as:
[tex]-12.2+x=-4.55[/tex]
[tex]-12.2+12.2+x=-4.55+12.2[/tex]
[tex]x=7.65[/tex]
Therefore, the scuba diver will travel a vertical distance of 7.65 meters.
