x hours to get there
\n" ); document.write( "4-x hours to get back
\n" ); document.write( "distance there is 45x miles
\n" ); document.write( "distance back is 50(4-x) miles
\n" ); document.write( "Those are equal
\n" ); document.write( "so 45x=200-50x
\n" ); document.write( "95x=200
\n" ); document.write( "x=2.105 hours to get there @45 mph=94.73 miles (rounded at end)
\n" ); document.write( "4-x=1.895 hours to get back @50 mph=94.73 miles
\n" ); document.write( "distance traveled was 189.46 miles
\n" ); document.write( "
