Fractions: Addition and Subtraction to Solve for Unknown Distance

The video tutorial explains how Ali completes a race consisting of a swim, a run, and a bicycle ride. The swim is 1/10 of the total distance, and the run is 3/10. The tutorial demonstrates how to calculate the fraction of the total distance that the bicycle ride covers by adding the fractions of the swim and run, and then subtracting from the whole. The result is 6/10, which is simplified to 3/5. The tutorial emphasizes understanding fractions and equivalent fractions.
