They're not necessarily.
In principle, the speedometer in the car is reading the instantaneous speed. And if you ask
"How fast were you driving at 10:31:46.0298427 AM yesterday ?", the answer would be an
instantaneous speed.
But if you ask "What's your speed for your trip to the office ?", then that's a trip that includes
turning corners, stopping for red lights, crowded streets, empty streets, fast stretches, slow
stretches, accelerating and decelerating several times, and pulling into the parking space at the
office. It comprises many different instantaneous speeds, so the answer has to be the average
for the whole trip.
averages in tests, bills, income, amount of time
That's because averages give us some idea about general tendencies.

The arithmetic mean, geometric mean and the harmonic mean are three example of averages.
(1,218/30) x ($3.60) = $146.16
i have had one for 3 years now. Averages around 32 mpg but on long run even at high motorway speeds can get up to 45mpg. Not sure where they get the 55 quoted on brochure. brilliant car. mark
Bad tires and bad alignment can cause the car to shake at certain speeds.
Your average car can reach speeds of up to 230km\h. The highest speed reached ever by a car is 413km\h.
Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds
The vehicle manual usually says what speeds to do in which gears.
a commercial car wash averages less than 45 gallons ...

A loud knocking noise in the motor of a car at high speeds is most likely the engine. There could be another issue with the transmission if the knocking only happens at high speeds.
A car that is jerking at high speeds probably needs a tune-up. Barring any major mechanical issue, this will solve the problem.
The cost of gas in the Bahamas averages about $1.47 per liter. This averages out to be about $5.49 per gallon.
