Justin gets a head start of
\n" ); document.write( " $\"+6%2A1.3+=+7.8+\"$ mi
\n" ); document.write( "They are then $\"+26+-+7.8+=+18.2+\"$ mi apart
\n" ); document.write( "----------------
\n" ); document.write( "Let $\"+d+\"$ = the distance Rhonda now has
\n" ); document.write( "to cover to meet Justin.
\n" ); document.write( " $\"+18.2+-+d+\"$ = distance Justin now has to cover
\n" ); document.write( "Let $\"+t+\"$ = the time it now takes them to meet
\n" ); document.write( "------------
\n" ); document.write( "After Justin's head start:
\n" ); document.write( "Justin's equation:
\n" ); document.write( "(1) $\"+18.2+-+d+=+6t+\"$
\n" ); document.write( "Rhonda's equation:
\n" ); document.write( "(2) $\"+d+=+8t+\"$
\n" ); document.write( "-------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+18.2+-+8t+=+6t+\"$
\n" ); document.write( "(1) $\"+14t+=+18.2+\"$
\n" ); document.write( "(1) $\"+t+=+1.3+\"$ hrs
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+18.2+-+d+=+6%2A1.3+\"$
\n" ); document.write( "(1) $\"+18.2+-+d+=+7.8+\"$
\n" ); document.write( "(1) $\"+d+=+18.2+-+7.8+\"$
\n" ); document.write( "(1) $\"+d+=+10.4+\"$
\n" ); document.write( "Justin has been running for $\"+1.3+%2B+1.3+=+2.6+\"$ hrs
\n" ); document.write( "Rhonda travels $\"+d+=+10.4+\"$ mi from home
