Step-by-step explanation:
Answer:
- 12 meters
28 meters
40 meters
Step-by-step explanation:
Given that:
A fish is 12 meters below the surface of the ocean. What is its elevation?
Position of fish = 12 meters below the surface = - 12 ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + (- 12)
= - 12 meters
2. A sea bird is 28 meters above the surface of the ocean. What is its elevation?
Position of bird = 28 meters below the surface = (28) ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + 28
= 28 meters
3. If the bird is directly above the fish, how far apart are they?
If bird is directly above the fish;
Distance between bird and fish :
Elevation of bird - elevation of fish
28 - (-12)
28 + 12
= 40 Meters
