Answer:
A. -12 meters
B. 28 meters
C. 40 meters
Step-by-step explanation:
The surface of the ocean would be 0.
Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.
For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.
Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
To solve such problems we need to know about the Elevation of an object.
Elevation
An elevation is defined as the height of an object above sea level. It is generally measured in meters or feet.
For example, a plane is flying at a height of 35,00 feet above the sea. so the elevation of the sea is 35,000 feet.
Given to us
- A fish is 12 meters below the surface of the ocean.
- A sea bird is 28 meters above the surface of the ocean.
A.) A fish is 12 meters below the surface of the ocean.
As the fish is below sea level, the elevation of the fish is negative. therefore the elevation of the fish is -12 meters.
B.) A sea bird is 28 meters above the surface of the ocean.
As the sea bird is above the sea. the elevation of the sea bird is 28 meters.
C). If the bird is directly above the fish,
If the bird is directly above the fish, the distance between them,
Distance between fish and bird = |(elevation of the fish)| + |(elevation of the sea bird)|
= |-12| + |28|
= 12 + 28
= 40 meters
Hence, the distance between them is 40 meters.
