A person can walk a certain distance and drive back in six hours. He can also walk both ways in 10 hours. How much time will he take to drive both ways?
\n" ); document.write( "(a) Two hours
\n" ); document.write( "(b) Two and a half hours
\n" ); document.write( "(c) Five and a half hours
\n" ); document.write( "(d) Four hours\r
\n" ); document.write( "\n" ); document.write( "He can walk both ways in 10 hours....so one way would take him 5 hours to walk. Now it took him 6 hours to walk there and drive back. We already know it takes 5 hours to walk there so it must take 1 hour to drive back. 1+1=2 so the answer is 2 hours.
