You can put this solution on YOUR website!
Use the formula d=rt.\r
\n" ); document.write( "\n" ); document.write( "John will catch Martina when their distances are the same.\r
\n" ); document.write( "\n" ); document.write( "Distance Martina travels is 24t\r
\n" ); document.write( "\n" ); document.write( "John's distance is 48(t-2), because he travelled 2 hours less but at a greater rate.\r
\n" ); document.write( "\n" ); document.write( "Distance are equal. \r
\n" ); document.write( "\n" ); document.write( "\"24t=48%28t-2%29\"\r
\n" ); document.write( "\n" ); document.write( "\"24t=48t-96\"\r
\n" ); document.write( "\n" ); document.write( "\"96=24t\"\r
\n" ); document.write( "\n" ); document.write( "\"t=4\"\r
\n" ); document.write( "\n" ); document.write( "In 4 hours, from Martina's starting time, John will catch her.\r
\n" ); document.write( "\n" ); document.write( "Therefore, 9 AM + 4 hours = 1 PM
\n" ); document.write( "
\n" );
