\n" ); document.write( "\n" ); document.write( "to mow a lawn \"10m\" by \"10m\" takes \"1h\",=> a lawn \"10m%2A10m=100m%5E2\" takes \"1h\"\r
\n" ); document.write( "\n" ); document.write( "to mow a lawn \"20m+%2A12m=240m%5E2\" takes \"t%2Ah\" (t hours)\r
\n" ); document.write( "\n" ); document.write( "time will be proportional to area \r
\n" ); document.write( "\n" ); document.write( "\"100m%5E2%3A1h=240m%5E2%3At%2Ah\"...solve for \"t\"\r
\n" ); document.write( "\n" ); document.write( "\"100m%5E2%2At%2Ah=240m%5E2%2Ah\"\r
\n" ); document.write( "\n" ); document.write( "\"100%2At=240\"\r

\n" ); document.write( "\n" ); document.write( "\"t=2.4h\" ....\"0.4h=0.4%2A60min=24min\"\r
\n" ); document.write( "\n" ); document.write( "\"t=2h\" and \"24min\" is an answer to the question how long will it take to mow a lawn \"20m\" by \"12m\"\r
