How long has the NFL played ever in seconds?

1.  Background Story: 

I watch a lot of football and i've noticed that there is is not a lot of actual playing time but I wonder how much there actually is.

I wonder how many seconds of actual playing time has there been in the NFL? 

2.  Ask Yourself This:  

How many seasons have there been?

How long is a game in seconds?

How many games have there been?

3.  Helpful Hints:  

32 teams in the NFL

512 games all teams play in a season

11 minutes on average in a game.

93 seasons ever since NFl and AFL merge

5,623 minutes played in a season

The NFL started in 1920 this year is 2013 that is about 93 years not counting this season because it is the middle of the season.

4.  Construct a Formula:

How many teams are in the NFl x How many minutes have there been total x How many games per season x sixty seconds = 31,426 

5.  Messy Math:  

11min  x  512games  =  5,623min    

1game  x 1season      =  1season

5,632min  x  93 seasons  =  523,776

1season    x           1             93 seasons

523,776

                                                                                 x_____60     1

                                    31,426,56x10
