A submarine was situated 800 feet below sea level. If it ascends 250 feet, what is its new position?

Answer:

550 ft below sea level

Explanation:

Let's assume a vertical axis pointing upwards. This means that the submarine, being 800 feet away from the horizon in the opposite direction with respect to the axis, will have a negative height of
h_0=-800

If it ascends 250 feets, it gains altitude, so the new height is
h_1=-800+250=-550

Note: this problem heavily depends on the coordinate system you adopt. In fact, I may have chosen an axes whose origin is set at the initial position of the submarine (which would have become the
h0=0), pointing upwards, and the new position would have been
h_1=0+250=250 feet.

Mark the word

  • Ascends:-The meaning of this word is to rise up from the level.

The submarine is rising up which means its distance from sea floor will decrease. So, we will Subtract the ascending value from the given value i.e.


\mathcal{NEW \: POSITION = \: 800 - 250}


\tt \: = 550 \: feet

Therefore, The new position of the submarine will be 650 feet below sea level...~
