Answer:

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
