\n" ); document.write( "-------------
\n" ); document.write( "Gigi DATA:
\n" ); document.write( "Time = 1 hr ; Distance = x km ; Rate = d/t = x kph
\n" ); document.write( "------------
\n" ); document.write( "Madel DATA:
\n" ); document.write( "Distance = 9-x km ; Rate = 2x kph ; Time = (9-x)/2x hrs
\n" ); document.write( "----------------
\n" ); document.write( "Comment: If Madel reached her house at the same time as Gigi reached
\n" ); document.write( "her house Madel's time is (3/4)hr.
\n" ); document.write( "---------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "(9-x)/2x = 3/4
\n" ); document.write( "6x = 36-4x
\n" ); document.write( "10x = 36
\n" ); document.write( "x = 3.6 km (Gigi traveled this far)
\n" ); document.write( "9-3.6 = 5.4 (Mdel traveled this far)
\n" ); document.write( "==============
