GCSE Secondary Maths Age 13-17 - Ratio, Proportion & Rates of Change: Inverse Proportionality - Explained

The video tutorial explains the inverse relationship between ocean water temperature and depth, using the formula T = 4500 / X. It demonstrates how to calculate temperature differences at depths of 1200 meters and 2500 meters, resulting in a difference of 1.95 degrees Celsius. The tutorial also guides viewers in identifying the correct graph that represents this inverse relationship, emphasizing the importance of understanding mathematical errors and graph behavior.
