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 2121.11 feet.\newline- She then rises 77.44 feet.\newline- Next, she descends a second time, 4747.66 feet.\newlineHow many feet must she now ascend to get back to sea level?\newlineAnswer: □\squarefeet
  1. Calculate Total Descent: Determine the total descent by adding the two descents.\newlineFirst descent: 21.121.1 feet\newlineSecond descent: 47.647.6 feet\newlineTotal descent = 21.121.1 feet + 47.647.6 feet\newlineCalculation: 21.1+47.6=68.721.1 + 47.6 = 68.7 feet
  2. Find Net Descent: Subtract the ascent from the total descent to find the net descent.\newlineTotal descent from Step 11: 68.768.7 feet\newlineAscent: 7.47.4 feet\newlineNet descent = Total descent - Ascent\newlineCalculation: 68.7−7.4=61.368.7 - 7.4 = 61.3 feet
  3. Determine Required Ascent: Determine the amount she must ascend to return to sea level.\newlineSince the scientist is currently at a net descent of 61.361.3 feet below sea level, she must ascend exactly that amount to return to sea level.\newlineCalculation: The scientist must ascend 61.361.3 feet.
