    if it takes a viking boat 20h to row across the Sea to England and 20h to row back,how many crossing could one boat make in a week?a year?

    please help me and correct me if im wrong ?
    20h-to row across the Sea to England
    20h-to row back
    HOW MANY CROSSING COULD ONE BOAT MAKE IN A WEEK?
    7daysx40h=280h so 280h:40h=7 -so 7 boats each week

    A YEAR?
    365daysx280h=10220h
    10220h:40h=255

    please correct me if im wrong

    there are 168 hours in a week. assuming the vikings rowed without a break... the number of return trips in a week will be the number of times you can fit 40 into 168.

    24 x 7=168 hours in a week
    168/20=8.4, 8 full crossings in one week (individually to England an back)
    52 weeks in a year
    52 x 8.4 =436.8, 436 full crossings in a year
    could be wrong,but I tried :erm:

    or 168/40=4.2 (including to England and back)
    4.2 x 52=218.4, 218 full crossings in a year

    That's right! But I think it makes more sense if you round down when giving your final answer.
