\n" ); document.write( "------
\n" ); document.write( "To work DATA:
\n" ); document.write( "rate = 80 mph ; distance = x miles ; time = d/r = x/80 hrs
\n" ); document.write( "-------
\n" ); document.write( "To home DATA:
\n" ); document.write( "rate = 25 mph ; distance = x miles ; time = x/25 hrs
\n" ); document.write( "----------------------
\n" ); document.write( "Equation::
\n" ); document.write( "time + time = time
\n" ); document.write( "x/80 + x/25 = 63/60
\n" ); document.write( "----
\n" ); document.write( "60*25x + 60*80x = 63*80*25
\n" ); document.write( "--------------------------------
\n" ); document.write( "1500x + 4800x = 126000
\n" ); document.write( "63000x = 126000
\n" ); document.write( "x = 126/63
\n" ); document.write( "x = 2 miles
