Question

A submarine was situated 450 feet below sea level. if it descends 300 feet. what is its new position?

Answer 1

Hey mate,

position of submarine before descending = 450 feet below sea level

[NOTE: descend means falling]

so after descending 300 feet new position = 450 + 300 = 750 feet below sea level.

Hope this helps

Answer 2

Given:

Position of submarine below sea level = 450 feet

Position of submarine descending = 300 feet

To Find:

New position of the submarine

Solution:

Position of the submarine (below sea level) = -450 feet

Position of the submarine after its descends = -300 feet

New position of submarine = Earlier position - Descending position

= (-450) + (-300)

= - 750 feet.

Answer: The negative sign shows that the ship is 750 feet below the level of sea
