f = p - 23\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "t = d / r ___ the time is the same for both trains\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "250 / (p - 23) = 450 / p\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "multiplying by p(p-23) ___ 250p = 450p - (23 * 450)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "23 * 450 = 200p
\n" ); document.write( "
