Question

If a submarine is at -24.2 feet below sea level at 5pm and then by 9pm it is at -136.12 feet. How far did it decend

into the ocean in 4 hours?

Answer 1

The submarine descended 111.92 feet into the ocean in 4 hours.

Step-by-step explanation:

To find the distance the submarine descended into the ocean in 4 hours, we need to determine the change in depth during that time. The submarine was at -24.2 feet below sea level at 5pm and at -136.12 feet at 9pm. To calculate the change, we subtract the initial depth from the final depth: -136.12 - (-24.2) = -111.92 feet. Therefore, the submarine descended 111.92 feet into the ocean in 4 hours.
