Simple question:- "What is the fastest speed that you have ever travelled?"

What if I told you that I knew the correct answer before you said anything?

Better still, what if I told you that the fastest speed you had ever travelled at was "approximately 64,000" Miles Per Hour (or 18 Miles Per Second). You would probably laugh your head off.

IT IS TRUE. The earth travels at approximately 64000 MPH.

Simple geometry. The sun is at the centre of the earth's orbit. The sun is aproximately 93 million miles away from earth. So the diameter of the earth's orbit is 186 million miles. Using the formula Pi times D where D is the diameter of the circle (orbit) and Pi is valued at 22/7 (or approximately 3) So roughly the earth travels 558 million miles in one year. Divide by 365 gives 1.529 million miles in one day. Divide again this time by 24 to find out how far the earth travels in one hour = Roughly 64,000 MPH

Isn't mathematics wonderful.

At the risk of making a fool of myself I thought pi was approximately 3.14 which increases the speed to 66,671 mph using your formula to calculate. Am I missing something in your example?

No, you are perfectly correct. I think I have covered myself by using the word "Approximately" here and there. I do that quite a lot with mathematics. Approximations are sometimes easier to arrive at, but give a broad idea of the finished result.

I love things like, instead of multiplying by 5, I add a zero and divide by 2. (Or, in reverse (i.e. divide by 5) really only works with large numbers, remove the last digit and multiply by 2. The answer is approximate, but close enough to give a working number.)

No problem, I wasn't trying to nitpick I just thought I must be missing some detail or it was a trick in some way.

It looks like that equation is only for the Earth's orbit. Then you have the rotation of the Earth itself when it is spinning in the same direction as the orbit is going. Then you could also add in the times you were on a plane or something that is traveling faster than the Earths rotation. There is some more math for you to play with...lol

For instance, sliding downhill after stepping on a banana skin.

When I was a child my grandfather was quite ill. My grandmother used to have to cover my grandfather's back with some sort of grease. He went downhill very quickly after that.

Don't laugh, you'll only encourage me. Ha ha ha.

How do you mean by speed??

Generally measured as the time taken to travel a certain distance.

The TIME for common reference is usually 1 hour.

Depending on your country's unit of measurement, either (Europe's) Kilometer or (USA and UK) Mile.

The result is written like KPH or MPH. For instance the roads in Britain are governed by a maximum of 70 MPH.

OK, since I am sure you didn't want a lecture on how to refer to SPEED, what was your question about.

You miss the 'actual' by quite a bit.
Not only is the Earth rotating and revolving around the Sun, the Sun is moving thru the Orion Arm of the Milky Way, the Milky Way is rotating and moving as a downward spiral to Sagittarius A (the Milky Way's Black Hole at its center).
The Milky Way is also orbiting within the Local Group and the Local Group is both spinning and orbiting within the Virgo Galactic Supercluster which is in turn spinning and orbiting within the Universe (string motion).
The Universe itself is currently expanding as well.

Then to really mess with your calculator consider quantum entanglement and atomic distances at a relative scale. Plus, don't forget thermodynamics related to matter in space-time.
Heat = Movement = Time

Mathematics aside... that may be the speed the Earth is going.
Travelling means "going from one place to another". Even though the Earth may be rotating, I am not going to another place at all. Unless of course I get walking/cycling/driving/ or in a plane.

So in that sense the answer to your question isn't correct.

If you only go by rotation of the Earth then even the Earth itself isn't 'travelling'. It's just rotating.
Like I can spin around without going anywhere.
Only if according to Tom's explanation the Earth IS moving through space could you say it is travelling.

Just had to reply to that last post.

In October 9th 2013 Colin Braun set a lap record at Daytona.

No one said that he (the driver) never went anywhere, but the distance he travelled was timed to produce a lap SPEED record.

I suppose, using your logic, you could say that your heart goes nowhere. Yet when talking about your heartbeat, it is calibrated at so many beats per minute. SPEED. You can't get away from it.

Well, OK, I haven't heard anyone (yet) saying that "the virus spread at 25 MPH". Ha ha ha.

Well, OK, I haven't heard anyone (yet) saying that "the virus spread at 25 MPH". Ha ha ha.

Well, if you think about it...
Viruses have what is called a transmission rate which is subject to population density and proximity.
So the virus does travel from host to host but at different speeds.
In dense areas (cities, schools, ships, etc...) the virus spreads faster than sparse areas (rural, farms, isolated areas, etc...)

Plus, some viruses have faster transmission rates than others.

Even though the Earth may be rotating

Actually, the Earth not only rotates, it wobbles and the tectonic places constantly move.

So, technically, even when you are in your bed fast asleep...you are traveling (moving). About the speed of the growth of a fingernail.

They move at a rate of one to two inches (three to five centimeters) per year.

But that's the not the same as speed of travel.
That the number of time something occurs within a set amount of time, like heartbeat is measured per minute. A rhythm or tempo. The heart isn't going anywhere.

Not certain what either would be called, but I think scientifically this is not the same thing.
