Brenda had driven $\"+65%2A5+=+325+\"$ km
\n" ); document.write( "They were 505 km apart, so $\"+505+-+325+=+180+\"$
\n" ); document.write( "Adam had driven $\"+180+\"$ km
\n" ); document.write( "Adam's equation:
\n" ); document.write( " $\"+180+=+45%2At+%7D%7D%7B%7D%0D%0A%7B%7B%7B+t+=+4+\"$
\n" ); document.write( "Adam drove for 4 hrs \n" ); document.write( "

\n" );
