13) D

HOPE IT HELPS

Step-by-step explanation:

7) 4 miles = 30 minutes

8 miles = 1 hour

12 miles = 1 hour 30 minutes

16 miles = 2 hours

20 miles = 2 hours 30 minutes

8) 1 miles = 1760

2 miles = 3520

3 miles = 5280

9) convert percentage into decimals

25% = .25

260 * .25 = 65

10) 1 gallon = 16 cups

12 x 16 = 192

11) 52:70*100

(52*100):70

5200:70 = 74.29

12) 60% / 100 = .6

.6 x 25 = 15

13) 1 liter = 1000 ml

18.75 x 1000 = 18750

18750 / 8 = 3750

The correct answer is:
