\n" ); document.write( "To Vegas DATA:
\n" ); document.write( "rate = 60 mph ; time = x hrs ; distance = 60x miles
\n" ); document.write( "---------------
\n" ); document.write( "From Vegas DATA:
\n" ); document.write( "rate = 64 mp ; distance = 72-x hrs ; distance = 64(72-x) hrs
\n" ); document.write( "----------------
\n" ); document.write( "Equation:::
\n" ); document.write( "distance = distance
\n" ); document.write( "60x = 64*72 - 64x
\n" ); document.write( "------
\n" ); document.write( "124x = 4608
\n" ); document.write( "----
\n" ); document.write( "x = 37.16 hrs
\n" ); document.write( "-----
\n" ); document.write( "Retrun trip took 72-37.16 = 34.84 hrs
