# what is your average velocity?

as i learned in basic physics this summer, average velocity = distance/time

distance = miles/kms/whatevers between where you started and where you are right now. if i was born in st. john’s hospital in yonkers and now reside in nyc, my distance would be 12.49 miles. it doesnt matter if i’ve moved/lived in a bunch of far-flung places in between, distance in this case is only the distance between my starting point and my (current) ending point.

my time is 27 years.

so my average velocity is 12.49/27 = .4625 miles/year.

my highest average velocity i’ve ever had would be approx. 8000/24 = 333.33 mpy

so what is your average velocity?

African or European?

OK - A more serious answer.

If you just go by birth to now, then it’s 739 miles in 42 years, or about 17.6 miles-per-year (0.02 miles per hour).

I think it’s more fun to put my waypoints in there. I’ve lived in 7 cities in the past 42 years for a total of 4549 miles in 42 years, or about 107 mpy (a smidge over a half-mile per hour).

Your highest average lifetime velocity, to be precise. Otherwise, you could easily do better. Just pick five minutes of your life from a plane ride, say.

Of course, questions arise: velocity relative to what? Should distances across the globe be measured in terms of the arc length along the surface or the actual straight-line distance through the Earth?

Going with reasonable answers of “You know what I mean”, my current average lifetime velocity is about 44 miles over 22 years = 2 mpy. My lifetime high would be about 3000 miles over 3 years = 1000 mpy.

Actually, I suppose I have an even higher high. When I was very young, I went on a trip to India. I can’t recall my exact age, but I believe I was about a year old. The total distance would’ve been about 8750 miles. So that makes a lifetime high of 8750 mpy.

7 miles / 30.5 years = 0.23 miles per year, or about 1.66 inches per hour, if my maths is right.

I have been around the world in that time, though.

2548 miles/37 years = 68.86 mpy

“Though the body may travel at the speed of sound, the soul travels as fast as a camel.”

If I add up all my long-distance travel over the years, I’m looking at at least 250,000 miles. So, 6,250 mpy, or in fact a measurable 0.7 mph.

However, where I’m currently sitting, about 1.5 mpy.

30.24 miles per year.

Fort Walton Beach FL to Brooklyn NY.

Going from the city to city distance on http://www.wcrl.ars.usda.gov/

7782 / 25.75 = 302 miles per year. What do I win?

No more than 1/2 mile a year or so - from a hospital in Chicago, to a suburb of Chicago. Maybe 25 miles in 47 years.

At work 4 mpy. When I’m at home .625 mpy. My best ever was living in Korea from 4-11 so I’ll go with 1458 mpy - 530 mpy.

I love conversion problems!

I live about 250 miles from where I was born 45 years ago.

3.35 feet per hour.

At 18 years old, when I lived in FL, it would have been 111 miles/year.

At 20, while I lived in Italy, it was 235.7 miles/year.

Now that I’m back in WI, it is a mere 7.14 miles/year

Or 4.3 feet/hr

Or relative to the center of the Milky Way Galaxy? The Sun?

Just over 19 furlongs per fortnight

I currently live within 1.5 miles of the hospital in which I was born, despite having travelled and lived many other distant places. I’m 33. So…

Yeah. Just to be clear, those two questions I mentioned were meant to be separate questions, so my first question was meant to be about just what you’re saying (things like “But relative to the sun, even staying put in Detroit, I’m traveling in a huge circle all the time”), and the second question was meant to be an independent one rather than some sort of expansion on the topic of the first one. (Though the second question probably doesn’t even make much sense unless you decide to adopt the point of view that Detroit is fixed, immobile throughout time. It’d be a bit odd to ruminate on the different distances between June Detroit and December Detroit as calculated along the surface of the Earth or in a straight line through it. I’m not sure what the former would even mean, in that context.)

And there are various other questions one could ask, I’m sure. But I imagine the best answer to them all is a quick “You know what I mean”, until something should possibly happen to make that untenable.

In a scientific sense, if you are talking relative to the Earth, your average velocity is probably a lot less than you think, and your estimates would also have to specify a direction.

Velocity (again, in the scientific sense of the word) is speed in a particular direction. So if you go 100 kph for one hour toward the northwest , and then go 100 kph for one hour toward the southeast, your overall average velocity is zero.

yes! thank you, canadjun, this is exactly the kind of distance i was thinking about. it doesnt matter if you walked all the way around the world, if you ended up in the same place, your distance would be zero.

in terms of “you know what i mean,” i meant relative to earth, not including how the earth moves around the sun or how the galaxy moves through space - i think if we were talking about how the galaxy moves through space then those miles would completely eclipse the miles you might have moved here on earth, so everybody’s velocity would be the same, which would be boring.

and ludovic, according to examples given by my physics professor, i think technically we are supposed to use actual straight-line distances through earth, but methinks that is way hard to figure out, so what i was thinking is a kind of “how the crow flies” distance over the surface of the earth from point a to point b.
