Let x be his speed:
\n" ); document.write( "25/x+1=30/x
\n" ); document.write( "Since he takes one hour longer going home.
\n" ); document.write( "Multiply both sides by x:
\n" ); document.write( "25+x=30
\n" ); document.write( "x=5
\n" ); document.write( "Of course, this should be obvious, Since it took him one hour to travel the 5 extra miles he needed to get home, his speed would naturally be 5mph.
\n" ); document.write( "
\n" );
