Ted's rate of working:
\n" ); document.write( "[ 40 bushels ] / [ 13 hrs ]
\n" ); document.write( "Katie's rate:
\n" ); document.write( "[ 40 bushels ] / [ 10 hrs ]
\n" ); document.write( "------------------------
\n" ); document.write( "Add their rates of working
\n" ); document.write( "to get their rate working together
\n" ); document.write( "Let \"+t+\" = time in hrs if they
\n" ); document.write( "work together
\n" ); document.write( "You can call 40 bushels 1 job, so
\n" ); document.write( "\"+1%2F13+%2B+1%2F10+=+1%2Ft+\"
\n" ); document.write( "Multiply both sides by \"+130t+\"
\n" ); document.write( "\"+10t+%2B+13t+=+130+\"
\n" ); document.write( "\"+23t+=+130+\"
\n" ); document.write( "\"+t+=+5.652+\" hrs
\n" ); document.write( "\"+.652%2A60+=+39+\"
\n" ); document.write( "It will take them 5 hrs 39 min working
\n" ); document.write( "together to pick 40 bushels
\n" ); document.write( "-----------------------------
\n" ); document.write( "check:
\n" ); document.write( "\"+1%2F13+%2B+1%2F10+=+1%2F5.652+\"
\n" ); document.write( "\"+.07692+%2B+.1+=+.17693+\"
\n" ); document.write( "\"+.17692+=+.17693+\"
\n" ); document.write( "close enough\r
