Why is harmonic mean used for speeds, not arithmetic mean?

In summary, when you are calculating the average of ratios of two quantities, (such as speed being the ratio of distance to time), if the values of the denominators are equal (equal time for each segment), then the average over all segments is the arithmetic mean of the ratios for for all of the segments.

When is harmonic mean used for all segments?

If the values of the numerators are equal (equal distance for each segment), then the average over all segments is the harmonic mean of the ratios for all of the segments.

How can you accelerate a car up a hill?

You can accelerate it up the hill by applying a positive acceleration. Until you slow it down entirely and it stops and turns around, you’re applying a positive acceleration to it, and it’s slowing down. Positive and negative are both relative terms: they depend on direction.

Why does my car lose power going uphill?

Reasons Your Car Loses Power Going Uphill 1) Bad Fuel Filter. You can’t have a good working engine without fresh pure gasoline flowing into it at all times. If you don’t have a good fuel filter to prevent the impurities of the fuel from flowing into the engine, then it could ultimately jeopardize the performance of your engine.

What causes a car to run lean on a hill?

If the fuel filter is not changed for a long time, eventually the particles and sediment from the gas tank will build up and clog the filter, restricting fuel flow. If the flow of fuel is restricted too much, not enough will be able to reach the fuel injectors and the car is likely to run lean.
