Javier B x mph
\n" ); document.write( "Maria A 7 faster
\n" ); document.write( "
\n" ); document.write( "Javier 51 miles
\n" ); document.write( "Maria 72 miles
\n" ); document.write( "Javier time = Maria time
\n" ); document.write( "
\n" ); document.write( "51 / x = 72 /( x + 7 )
\n" ); document.write( "cross multiply
\n" ); document.write( "51 ( x + 7 ) = 72 x
\n" ); document.write( "51 x + 357 = 72 x
\n" ); document.write( "72 x - 51 x = 357
\n" ); document.write( "21 x = 357
\n" ); document.write( "/ 21
\n" ); document.write( "x = 17 mph Javier
\n" ); document.write( "
\n" ); document.write( "24 mph Maria \r
