A scuba diver is 22 feet below sea level. Their friend is standing on a diving board 9 feet above sea level. What is the vertical distance between the scuba diver and their friend?

Answer 1

The sum \( -22 + 9 \) can be interpreted in the context of measuring how much warmer it is today compared to yesterday when dealing with temperatures. Therefore, the correct real-world problem that could be solved with the sum is:

The temperature was −22°F yesterday. Today the temperature is 9°F. How much warmer is it today compared with yesterday?

This scenario directly involves the addition of a negative and a positive number, reflecting a change in temperature from a below-zero value to a positive value.
