Leang's Walking Rate and Inequalities

The video tutorial covers the sixth-grade concept of writing one-step, one-variable equations and inequalities, focusing on a problem from the 2017 released STAR test. The problem involves Lang's goal of walking at least 18 miles at a rate of 4 miles per hour. The tutorial uses a number line to visualize the problem and explains the concept of 'at least' in terms of inequalities. It guides viewers through solving the inequality to determine the number of hours Lang needs to walk to meet or exceed her goal.
