Final answer:
The ordered pair (6, 72) shows an equivalent ratio of hours to miles.
Step-by-step explanation:
To find the equivalent ratio of hours to miles, we need to determine the common factor between the given hours and miles in each ordered pair. Let's calculate:
- (6, 72): Divide both numbers by 6 to get the ratio 1:12.
- (72, 6): Divide both numbers by 6 to get the ratio 12:1.
- (8, 84): Divide both numbers by 4 to get the ratio 2:21.
- (120, 10): Divide both numbers by 10 to get the ratio 12:1.
Therefore, the ordered pair (6, 72) shows an equivalent ratio of hours to miles.
