slower train speed r\r
\n" ); document.write( "\n" ); document.write( "time 7\r
\n" ); document.write( "\n" ); document.write( "distance 7r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "fast train speed r+150
\n" ); document.write( "time 2\r
\n" ); document.write( "\n" ); document.write( "distance (r+150)*(2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "at t=7 distance are equal
\n" ); document.write( "(r+150)(2)=7r
\n" ); document.write( "2r+300=7r
\n" ); document.write( "r=\"60\" mph
\n" ); document.write( "faster train speed is \"210\"\r
