WebFor example, the harmonic mean of the five values: 4, 36, 45, 50, 75 is + + + + = = Relationship between AM, GM, and HM. Proof without words of the inequality of arithmetic and geometric means: is the diameter of a circle centered on ; its radius is the arithmetic mean of and . Using the ... In many situations involving rates and ratios, the harmonic mean provides the correct average. For instance, if a vehicle travels a certain distance d outbound at a speed x (e.g. 60 km/h) and returns the same distance at a speed y (e.g. 20 km/h), then its average speed is the harmonic mean of x and y (30 km/h), not the arithmetic mean (40 km/h). The total travel time is the same as if it had traveled the whole distance at that average speed. This can be proven as follows:
