Answer:
A and C
Step-by-step explanation:
There should be a 3:1 ratio from the miles to the hours. 3:1 is equivalent to 9:3 with a scale factor of 3. It is also equivalent to 3/4:1/4 with a scale factor of 1/4. Ergo, A and C are the answers. B and D wouldnt be the answers because they have a 1:3 ration instead
