208 miles in one direction during a snow storm.
\n" ); document.write( "return trip double the speed and took 4 hours less.
\n" ); document.write( "..
\n" ); document.write( "let speed while going be xmph
\n" ); document.write( "speed returning will be 2x mph
\n" ); document.write( "..
\n" ); document.write( "time taken while going = 208/x
\n" ); document.write( "time taken on return = 208/2x, 4 hours less
\n" ); document.write( "208/x -4 = 208/2x\r
\n" ); document.write( "\n" ); document.write( "208/x-208/2x= 4
\n" ); document.write( "416-208 /2x=4
\n" ); document.write( "208= 8x
\n" ); document.write( "x=26 mph speed while going
\n" ); document.write( "
\n" );
