I’m confused. Does this math check out? 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

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?
- re 2y agoI think the parent comment was confusing/misremembering the rotational speed value in miles per hour as miles per second.
- thsksbd 2y agoI got the same answer
- Choco31415 2y agoEven if we stretch out and look at how fast the Earth orbits the sun, it still doesn't explain the 4 mile figure. Earth's orbital speed: 66,200 mph 66,200 mph / 3600 s/h = 18.38 mps 18.38 * (1/250) = 0.07 miles
- mrb 2y agoYou are correct. Using GNU units: $ units '2 * pi * earthradius / day * (second / 250)' Definition: 1.8532517 m Which is 0.0011515572 miles...
- tomrod 2y agoI think it's relative and phrased poorly, since the orbiter has to circle the earth at a certain faster speed. But quick googling shows Apollo 8 was traveling about a mile a second?
