Ahelicopter is hovering 100 meters above the ocean. directly below it, a submarine is at a depth of 200 meters. the altimeter on the helicopter reads meters, which means it is 100 meters sea level. the altimeter on the submarine meters, which means it is 200 meters sea level

1. 100

2. Above,

3. ,

4. Below.

Step-by-step explanation:

We have been given that a helicopter is hovering 100 meters above the ocean. Directly below it, a submarine is at a depth of 200 meters. We are supposed to fill in the given blanks.

We know the helicopter is 100 meters above the sea level, so its altitude will be positive 100.

The altimeter on the helicopter reads 100 meters, which means it is 100 meters above sea level.

We know the submarine is at depth of 200 meters, which means that it is 200 meters below the sea level, so its altitude will be negative 200.

The altimeter on the submarine reads meters,which means it is 200 meters below sea level.
