The video tutorial explains how to graph speed using a distance and time graph. It covers the concepts of independent and dependent variables, with time as the independent variable and distance as the dependent variable. The tutorial describes motion on the graph from points A to B and B to C, and how to calculate average speed using the slope of the graph. Example calculations are provided to illustrate these concepts.
