Answer: It takes 12 minutes to run each mile.

Step-by-step explanation:

Given: It takes Beth 157.2 minutes to run a 13.1 mile race.

i.e. Time taken to run 13.1 miles  = 157.2 minutes

Then, Time taken to run 1 mile = [tex]\dfrac{\text{Time taken to run 13.1 miles }}{13.1}[/tex]

[tex]\dfrac{157.2}{13.1}\\\\=\dfrac{1572}{131}\\\\=12\text{ minutes}[/tex]

Hence, it  takes 12 minutes to run each mile.
