thx... but wouldn't that be 24hr*365days=8760hrs per year/18hrs=486.6666 times as fast as the earth?

It looks like you are assuming they are at the same distance from the star. The orbital path length of one is 8,700,000 miles based on a radius of 1,384,000 miles. The orbital path length of the Earth is 584,300,000 miles based on a radius of 93,000,000 miles. 8,700,000 miles/18 hrs = 483,333 mi/hr. For Earth, 584,300,000 miles/(365.25*24) hours = 66659 mi/hr. Computing the ratios of the two speeds we get 483.333/66659 = 7.25.

483.333/66659 = 7.25.

Typo. Should be

483,333/66659 = 7.25.
