"Each mile she runs beyond 2 miles, her speed slows 1 mile a minute."

Are you sure it is "1 mile a minute" and not "1 minute a mile"?

No one runs fast enough to slow down by 1 mile a minute!

I will assume the problem says that for every mile she runs beyond 2 miles she takes an extra minute to run 1 mile.

She runs the first 2 miles in 8 minutes steady.  So she takes 4 minutes per mile.

For every extra mile after the first 2 miles she takes a minute longer per mile.
So for the third mile she takes 5 minutes
The fourth mile  she takes 6 minutes 
The fifth mile  she takes 7 minutes 

Add them all up along with 8 minutes for the first 2 miles.

Total of 8 + 5 + 6 + 7 = 26 minutes to run the 5 miles.
