    400 minutes

    Step-by-step explanation:

    To solve this problem we need to divide 520 by the rate and then multiply that answer by 5 minutes.

    520 / (6 1/2)

    520 / (13/2) "Changing to improper fraction."

    520 * 2/13 "Dividing by a fraction is the same as multiplying by its reciprocal.

    1040/13 = 8

    5*80=400
