The video tutorial covers the calculation of unit rates and equivalent ratios to solve a problem involving Hank, who paints hotel rooms. It is divided into four parts: calculating the time to paint six rooms, determining the unit rate for one room, writing an equation for any number of rooms, and finding the total number of rooms painted in 1200 hours. The tutorial uses proportions, cross-product properties, and algebraic equations to teach these concepts.
