y = 2/3 sq-yrd/hr
\n" ); document.write( "f - 4/5 sq-yrd/hr\r
\n" ); document.write( "\n" ); document.write( "y + f = 2/3 + 4/5
\n" ); document.write( "10/15 + 12/15 = 22/15 sq-yrd/hr
\n" ); document.write( "---
\n" ); document.write( "t = a/r = 11 / (22/15)
\n" ); document.write( "11 * 15 / 22 = 7.5 hours
