Answer 1

A temperature of 11 degrees is warmer than -15 degrees. Anything in the negative numbers is frigid.

An elevation of 10 feet is farther than -8.

The temperature was 8 - 10 degrees = -2 degrees at midnight.

25 feet -15 feet = brings him to 10 feet below sea level.

A. 0 feet

B. 300 feet below sea level

C. 450 feet below sea level
