\n" ); document.write( "With \"1%2F3\" of work completed by both, in 4 hours, \"matrix%281%2C7%2C+1+-+1%2F3%2C+or%2C+2%2F3%2C+of%2C+work%2C+remains%2C+undone%29\"
\n" ); document.write( "With Edward taking 18 hours to do entire job alone, and doing \"1%2F18\" of job in 1 hour, time (T) taken by Edward to complete remaining \"2%2F3\" of job is:
\n" ); document.write( "T, or time taken by Edward to complete remaining \"2%2F3\" of job = \"highlight_green%28highlight%28matrix%281%2C2%2C12%2C+hours%29%29%29\" \n" ); document.write( "
