Answer:
(I can't figure out number one)
2. 7 1/2 feet below sea level or -7 1/2 feet
3. It would stop on the 17th floorl
Step-by-step explanation:
2. You subtract 20 1/2 by 28 to get your answer. Flipped around, 28 - 20 1/2 is 7 1/2 so back to the right way would be -7 1/2 or 7 1/2 feet below sea level.
3. 23 + 5 = 28
28 - 14 = 14
14 + 3 = 17
So the 17th floor would be the answer.
