You need to write 2 equations, 1 for each of you.
\n" ); document.write( "This problem assumes a lot of things, like you can
\n" ); document.write( "drive at a constant speed from a standing start.
\n" ); document.write( "---------------
\n" ); document.write( "You will each travel the same distance to where you meet.
\n" ); document.write( "You will each travel for 30 seconds
\n" ); document.write( "Let $\"d\"$ = the distance each will travel
\n" ); document.write( "Let $\"s\"$ = your speed
\n" ); document.write( "---------------
\n" ); document.write( "Other car:
\n" ); document.write( " $\"+d+=+60%2A.5+\"$
\n" ); document.write( " $\"+d+=+30+\"$ miles
\n" ); document.write( "Your car:
\n" ); document.write( " $\"+d+=+s%2A.5+\"$
\n" ); document.write( "----------------
\n" ); document.write( " $\"+30+=+.5s+\"$
\n" ); document.write( " $\"+s+=+60+\"$
\n" ); document.write( "You must drive 60 mi/hr \n" ); document.write( "
