\n" ); document.write( "The two trains will be 50 miles apart after one hour.

\n" ); document.write( "So if the two speeds in miles per hour are x and x+10,

\n" ); document.write( " $\"x%5E2%2B%28x%2B10%29%5E2+=+50%5E2\"$
\n" ); document.write( " $\"x%5E2%2Bx%5E2%2B20x%2B100+=+2500\"$
\n" ); document.write( " $\"2x%5E2%2B20x-2400+=+0\"$
\n" ); document.write( " $\"x%5E2%2B10x-1200+=+0\"$
\n" ); document.write( " $\"%28x%2B40%29%28x-30%29+=+0\"$

\n" ); document.write( "You can finish.... \n" ); document.write( "
