To better compare the rates, we can change his speed into minutes per mile.
As a boy he ran miles in minutes, which means that he ran at a pace of minutes per mile.
As an adult, he can walk miles in minutes, which means he walks at a pace of minutes per mile.
Subtracting the two, we get that he takes more minutes to walk a mile as an adult.
Thus, B is the correct answer.
