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 <math>60</math> minutes in a hour. Therefore, there are <math>11 \cdot 60 = 600 + 60 = 660</math> minutes in 11 hours. Adding the second part, we get <math>660 + 5 = \boxed{665}</math>.
So, multiply <math>11</math> and <math>60</math> because we need to convert <math>11</math> hours into minutes.
 
You will get <math>660</math>.
 
Now, add <math>660</math> and <math>5</math> to get the total minutes.
 
The answer is <math>\boxed{\text{(C) } 665}</math>

The longest professional tennis match ever played lasted a total of $11$ hours and $5$ minutes. How many minutes was this?

$\textbf{(A) }605\qquad\textbf{(B) }655\qquad\textbf{(C) }665\qquad\textbf{(D) }1005\qquad \textbf{(E) }1105$

Solution

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 $11 \cdot 60 = 600 + 60 = 660$ minutes in 11 hours. Adding the second part, we get $660 + 5 = \boxed{665}$.
