Assume that the planet’s orbit is circular at a radius 500 million kilometers from its star.
\n" ); document.write( "Determine the speed of the planet (miles/second) around the star if there are 300 earth days in its year.
\n" ); document.write( "------------
\n" ); document.write( "Find the circumference, convert to miles.
\n" ); document.write( "Divide that by 300 --> miles/day
\n" ); document.write( "Divide by 86400 --> mi/sec
\n" ); document.write( "
\n" );
