Subtracting Rational Numbers in Real-World Contexts

The video tutorial teaches how to subtract rational numbers using real-world contexts. It begins with an introduction to the concept, followed by a review of subtracting by adding the additive inverse. The tutorial includes examples such as calculating the distance between a hot air balloon and a scuba diver, and solving problems involving an airplane and a submarine. Another example involves calculating temperature changes. The lesson emphasizes the importance of checking if answers make sense and concludes with a summary of the key points.

Explain how to find the distance between two objects at different heights.
