Really this is not homework, I'm 30 years old.

If a moon's velocity is 300 meters/second and it's orbiting a planet whose velocity is 500 meters/second, what is its actual velocity through space, or the equation to find it ?

Thanks,

Christine

I don't know where you got those numbers. The moon goes around the Earth at the rate of about

1000m/s and the Earth goes around the sun at the rate of about 30000m/s. There's no way to calculate the velocity through space since there's no reference position.
