Question #1
\n" ); document.write( "You are starting with 186000 MILES per SECOND, and you want the distance for the amount of time 365 days.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"186000%28miles%2Fsecond%29%2AchainOfUnitConversionFactors\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The time units are what you mostly want to identify and use.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You may find in the process an expression equivalent to
\n" ); document.write( "\"1.86%2A3.6%2A2.4%2A3.65%2A10%5E12\"
