Scuba Diving (Multiply rational numbers in a real-world example)

The video tutorial explains how Jim, an experienced scuba diver, adjusts to pressure changes by stopping every 28.5 feet. Starting at sea level, Jim's altitude decreases by 28.5 feet each time he stops, resulting in a total drop of 85.5 feet after three stops. The lesson demonstrates how to multiply rational numbers, emphasizing the importance of determining the sign of the product when multiplying a negative and a positive number. The tutorial concludes by summarizing the key points learned about multiplying rational numbers in real-world scenarios.

Explain why the product of the two factors is negative.
