The video tutorial covers two examples of time calculations: adding and subtracting time. The first example involves calculating the total flying time for a trip with two flight segments, requiring the conversion of minutes to hours. The second example involves determining the wait time between two movies, necessitating the subtraction of time and conversion of hours to minutes. The tutorial explains the process of aligning time units and performing necessary conversions for accurate results.
