2. A submarine starts out at 135 feet below sea level.It dives 239 feet before rising 307 feet. Represent the current depth of the submarine as an integer.
Accepted Solution
A:
Answer:The submarine is at 67 feet below the sea level (-67)Step-by-step explanation:* Lets explain how to solve the problem- The zero level is the sea level- Any height below the sea level is negative- Any height above the sea level is positive- A submarine starts out at 135 feet below the sea level∴ The submarine is at -135 feet- The submarine dives 239 feet before rising∴ The submarine dives another -239∴ The submarine is at -135 + -239 = -374 feet* The submarine is at 374 feet below the sea level- The submarine rising 307 feet∴ The submarine dives 307 feet up- Add the last position to the rising distance∴ The current depth of the submarine = -374 + 307 = -67 feet∴ The submarine is at 67 feet below the sea level
