speed=distance/time=2PI*radius/164.8 years
now, convert years to seconds and you have it.
Earth speeds along at 29.8 km/s in its orbit. Neptune's nearly circular orbit has a radius of 4.5 x 109 km, and the planet takes 164.8 years to make one trip around the Sun. Calculate the speed at which Neptune plods along in its orbit.

yes i solve it like this but we will not need the speed of the earth ?
Bot please help
Neptune orbits the sun in about 1.45×10⁶ hours at a speed of about 1.95×10⁴ km per hour approximately what distance in km does Neptune travel in one orbit
