Given that earth orbits at 150,000,000 km from the sun, through what distance does earth move in a second?

First we know that Earth moves around the sun once per year.

If Radius = 150,000,000Km, then the circumference of Earth's orbit must be:

C = 2 x R x Pi

C = 2 x 150,000,000 x 3.141529

C = 942,458,700Km per year

Divide that by 365.25 days, and we get:

C = 2,580,311Km per day

Further divide that by 24 hours and we get:

C = 107,512Km / hour

There are 3600 seconds in an hour so:

C = 29.86 km / second
