There are several things wrong with this problem.
\n" ); document.write( "1) The teacher could not leave any of the students alone.
\n" ); document.write( "2) How does the teacher have her car if they are on the bus field trip?
\n" ); document.write( "3) If the students were left alone they would not all walk. Some would stay; most would get on their cellphone to text or twitter but certainly not walk!
\n" ); document.write( "You can barely get them to walk in gym class.
\n" ); document.write( "4)I don't think so! Most students have never walked more than a mile before in their life.\r
\n" ); document.write( "\n" ); document.write( "It would take one hour to drive to school and another hour drive back.
\n" ); document.write( "So the students have walked 8 miles for two hours. \n" ); document.write( "
