For each, \"d+=+r%2At\"
\n" ); document.write( "For each \"t+=+2\"hrs
\n" ); document.write( "For the 1st plane, \"r+=+150\" mi/hr
\n" ); document.write( "For the 2nd plane, \"r+=+200\" mi/hr
\n" ); document.write( "\"d%5B1%5D+=+150%2A2\"
\n" ); document.write( "\"d%5B1%5D+=+300\" mi
\n" ); document.write( "\"d%5B2%5D+=+200%2A2\"
\n" ); document.write( "\"d%5B2%5D+=+400\" mi
\n" ); document.write( "They traveled apart at right angles to eachother, so
\n" ); document.write( "their distance apart is \"d+=+sqrt%28%28300%29%5E2+%2B+%28400%29%5E2%29\"
\n" ); document.write( "\"d+=+sqrt%289%2A10%5E4+%2B+16%2A10%5E4%29\"
