1. 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
2. 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.
3. How many hours are in a week?

How many hours are in a year?
4. 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
5. or 168/40=4.2 (including to England and back)
4.2 x 52=218.4, 218 full crossings in a year
6. That's right! But I think it makes more sense if you round down when giving your final answer.
