Add their rates of jogging together since they are jogging in opposite directions, and multiply by the time:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(5 1/2 + 4 3/4)*(1 1/4)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, there are three ways to do this!
