\n" ); document.write( "Let  D  be an unknown distance to Alton.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If Gina drives at  60 km/h,  she will spend  \"D%2F60\"  hours,  or  \"%28D%2F60%29%2A60\" = \"D\"  minutes to get Alton.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If Gina drives at  90 km/h,  she will spend  \"D%2F90\" hours,  or  \"%28D%2F90%29%2A60\" = \"%282%2F3%29%2AD\"  minutes to get Alton.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "According to the condition,  the difference of these times is  40  minutes.  It gives you an equation to determine  D:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"D\" - \"%282%2F3%29%2AD\" = \"40\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The solution is  D = 120 km.\r
