Answer 2

(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

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.
