\n" ); document.write( "----
\n" ); document.write( "slower car DATA:
\n" ); document.write( "rate = 30 mph ; time = x hrs ; distance = rt = 30x miles
\n" ); document.write( "----
\n" ); document.write( "faster car DATA:
\n" ); document.write( "rate = 60 mph ; time = x-2 hrs; distance = rt = 60(x-2) miles
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "distance = distance
\n" ); document.write( "30x = 60(x-2)
\n" ); document.write( "30x = 60x - 60*2
\n" ); document.write( "---
\n" ); document.write( "30x = 60*2
\n" ); document.write( "x = 4 hrs (time for faster to catch up to slower)
