Problem
The longest professional tennis match ever played lasted a total of 
hours and 
minutes. How many minutes was this?
Solutions
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 
minutes in a hour. Therefore, there are 
minutes in 11 hours. Adding the second part(the 5 minutes) we get 
.
Solution 2
The best method comes when you remember your multiplication tables. Thus trivial, we get our answer of 
.
Solution 3
11 hours 5 min = (11 * 60) + 5 min = 665 min, therefore
.
