Great lyrics
That's a fun listen.
Heh. I'd never read/heard that quote before. But no one's photos have touched me more than Galen Rowell's, so it bears an incredible amount of weight to read.
Thank you for sharing it.

Circumference is 24,901 - so about 1000 mph at equator.
1000 mph / 3600 s / h = 0.27 mps
0.27 * (1/250) = 0.001 miles?
Doing this math on my phone but am I missing something here?
Earth's orbital speed: 66,200 mph
66,200 mph / 3600 s/h = 18.38 mps
18.38 * (1/250) = 0.07 miles
$ units '2 * pi * earthradius / day * (second / 250)'
Definition: 1.8532517 m
360/86,400=0.0041667deg/sec
0.0041667 * 0.004sec = 000016667degR
circumference:
2pi * 6371km = 40,030km
land covered by rotation:
40,030 / 360 = 111.194km/deg
0.000016667deg × 111.194 km/degree = 0.001854 km
km to m:
0.001854km × 1,000 meters/km = 1.854 meters
more like 0.001 miles. ... oh, woops. I see your answer is in kms.
it was something like 0.46km/s.
$ units "2 * pi * moondist / (27.3 day) * (second / 250)"

Or if the orbital velocity was 17,000 mph and neglecting the height of the orbit, 17000 / 3600 / 250 = 0.018 miles.
So either way, about 100 feet.
