Answer:
12/17 miles
Step-by-step explanation:
Make the denominators equal -> 1/4 = 17/68, 3/34 = 6/68
17/68 inches represent 2 miles
The ratio between 17/68 and 6/68 is 17/68 : 6/68 = 17/6
So, the ratio between the distance should also be 17/6
-> 3/34 inches represent 2 : 17/6 = 12/17 (miles)
Hope it helps :)
