Distance = rate multiplied by time of travel.\r
\n" ); document.write( "\n" ); document.write( "60x + 30x = 150\r
\n" ); document.write( "\n" ); document.write( "90x = 150\r
\n" ); document.write( "\n" ); document.write( "x = 150/90\r
\n" ); document.write( "\n" ); document.write( "x = 15/9\r
\n" ); document.write( "\n" ); document.write( "x = 5/3 hours
