    A long wooden block is lying there.
    If it takes five minutes to cut a piece of ten feet long from it , how long will it take to cut it into ten pieces of one foot each ?

    Thank you for your response.
    I don't think it is correct. But how did you arrive at it ?

    It takes 5 minutes to cut 10 feet long so it takes 2 minutes to cut 1feet long. 20 minutes take to cut 10 pieces of 1 feet long...am I right?
    May I know your version please

    There is a wooden log which measures more than ten feet .
    It is marked at the tenth feet and cut once. For this single cutting it takes five minutes.
    When this measured piece is cut at nine points , namely, first foot, second foot, ......
    and ninth foot , LEAVING THE TWO ENDS , we have to make nine cuttings, each taking five minutes .
    Hence 9×5=45 minutes.
    (By the way , pl. check your calculation of five minutes for ten feet ).
