I am not sure what a plain mile is but I am guessing it has no mayo or ketchup.

If a plain mile and a nautical mile are different, how do we know that the earth is 25,000 miles around?

1 road mile is 1.150779 nautical miles

nautical mile = 6000 feet
road mile = 5280 feet

OK, here is one for everyone..... what is the speed of sound?

I am guessing that mtngrrl meant that 1 nautical mile = 1.15... road miles since it has more feet in it

dyslexia anyone?

in my life, it is how fast MsGilmore can hear that I have put cash in my wallet...

for the rest of the world - the speed of sound varies depending on the temperature, pressure, and density of the medium through which the sound waves travel. For dry air at sea level at 68° F, the speed of sound is 767 miles per hour, or 1235 km/h

BOOM!!!

About the same speed as the common high-velocity .22 Long Rifle cartridge, assuming it is fired from a rifle.

What is the air speed velocity of an unladen swallow?

i think it depends on if you are swallowing liquids, solids, or a combination of both...

What is the speed of quiet?

African or European?

Based upon published species-wide averages of wing length and body mass, initial Strouhal estimates based on those averages and cross-species comparisons, the Lund wind tunnel study of birds flying at a range of speeds, and revised Strouhal numbers based on that study gives an estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles per hour.


if that helps

And if carrying a coconut?

a 5 ounce bird cannot carry a one pound coconut

What if two of them carried it together. They could grip the husk with their talons.

Well, you have to know these things when you're a king, you know.

Listen. In order to maintain air-speed velocity, a swallow needs to beat its wings forty-three times every second, right? ... Am I right?

Unless he is gripping a coconut by the husk

Oh yeah, an African swallow, maybe, but not a European swallow. That's my point.

... But then the African swallow's not migratory...

The rescued reportedly plan to plant trees to offset the carbon their rescue is generating, demonstrating that in the face of the cognitive dissonance generated by the failure of Antarctic ice to diminish, they are clinging even more strongly to the beliefs which have not worked out as predicted.

I do not think that the trees will take in the arctic or do thye plan to plant them in NJ.

Are these trees being planted with heavy machinery running on fossil fuel?

In contrast, Tom Crean (the explorer not the basketball coach), on his third voyage to the Antarctic, was also on a ship that was trapped in the ice, and crushed by the ice, and sunk. After hiking over ice and sailing in small boats to escape with his mates, Tom went back to Annascaul, County Kerry, Ireland and opened a pub called the South Pole Inn, where he spent the rest of his days. I have had a pint of Guinness in Tom's pub.

Much better plan than planting trees.
