Question

the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational manuever increased it's depth by 15 1/2 feet. What is the position of the submarine now relative to the water surface?

Answer 1

Position of the submarine now relative to the water surface
`=-47\ (3)/(4)`

Explanation:

It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.

Now we need to find about what is the position of the submarine now relative to the water surface.

Downward navigation means we 15 1/2 is negative

so we will just add both values to get the final answer:

Position of the submarine now relative to the water surface =
`-32\ (1)/(4)-15\ (1)/(2)`

`=-32\ (1)/(4)-15\ (2)/(4)`

`=-47\ (3)/(4)`
