解析 · Solution
Solution 1
It is best to split 11 hours and 5 minutes into 2 parts, one of 11 hours and another of 5 minutes. We know that there is 60 minutes in a hour. Therefore, there are minutes in 11 hours. Adding the second part(the 5 minutes) we get 660 + 5 = 665.
The best method comes when you remember your multiplication tables. Thus trivial, we get our answer 665.
11 hours 5 min = , therefore 665. Carmen
