\n" ); document.write( "\n" ); document.write( "Work- I tried to examine what the problem gave me. She walks 2 km uphill and 6 km down hill, but there was no clarification in the problem that she even walked on a hill. So, the fact that she walks 3 km on level ground is almost as obsolete because there's no guarantee that she walked on a level surface either. I did the work assuming that she would walk an entirely flat surface which is obviously 3x6=18km. If I assume she goes up and down each for an hour and the rest is flat it's 4+12+6=22km. If I find the average speed she walks (3x2x6/3) then I get that she walked 12 km. I feel like I could figure this problem better if I just knew what information from the original problem I am missing. \n" ); document.write( "
