You can put this solution on YOUR website!
In the \"first three hours, you drive 50 mph\", so you've driven 3*50 = 150 miles so far\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You need to travel the remaining 300 - 150 = 150 miles at 65 mph\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So this will take you about 150/65 = 2.30769 hours
\n" ); document.write( "
\n" );
