Q. A scientist uses a submarine to study ocean life.\newline- She begins at sea level, which is an elevation of o feet.\newline- She travels down 9898.88 feet.\newline- She then rises 6363.55 feet.\newline- Next, she descends a second time, 3232.11 feet.\newlineHow many feet must she now rise to get back to sea level?\newlineAnswer: □\squarefeet
  1. Initial Descent: First, let's consider the initial descent of the submarine. The scientist starts at sea level and descends 98.898.8 feet.
  2. First Ascent: Next, the scientist ascends 63.563.5 feet.\newlineTo find the new depth, we subtract the ascent from the initial descent.\newline98.898.8 feet −- 63.563.5 feet == 35.335.3 feet\newlineThe scientist is now 35.335.3 feet below sea level.
  3. Second Descent: Then, the scientist descends another 32.132.1 feet.\newlineWe add this descent to the current depth to find the new depth.\newline35.335.3 feet + 32.132.1 feet = 67.467.4 feet\newlineThe scientist is now 67.467.4 feet below sea level.
  4. Return to Sea Level: Finally, to determine how many feet the scientist must rise to get back to sea level, we consider the current depth below sea level.\newlineThe scientist must rise 67.467.4 feet to return to sea level.
