Step-by-step explanation:
Since Jackie wants her new map to be three times larger, then you would have to take a look at her ratios.
the original ratio is 1 inch:12ft, which basically says for every inch on the map you would get 12 real-life feet.
to get the ratio of her new map, just multiply the second half of the ratio times three. the inch should remain the same.
I hope i helped you out!
