Question

b. A submarine is at a depth of 453 ft below sea level. It further descends by 87 ft. Where is
the submarine now?
SOLVED STEP BY STEP​

Answer 1

Answer:

tpo initial position of submarine=453 ft below sea level= -453

later it descends 87 ft=-87

the current position of sub marine=(-87)+(-453)

= -540

therefore now the submarine is at 540 ft below the sea level.

Answer 2

Answer:

The position of the submarine is 540ft below the sea level

Step-by-step explanation:

Given,

The depth of the submarine = 453ft below sea level

It further descends 87ft.

To find,

The position of the submarine now

Solution:

Since the submarine further descends by 87feet, the distance of the submarine from the sea level increased by 87 feet from the earlier position.

That is, the position of the submarine is 87 more than the original position.

The position of the submarine now = 87more than 453

= 87 + 453

= 540

∴ The position of the submarine is 540ft below the sea level
