Answer:
D. 343 3/4
Step-by-step explanation:
1 inch = 125 miles
There is a distance of 2 3/4 inches
The first thing you would do is double 125, since it is one inch, and 2 inches would another 125. Now you have 250. To get the rest, you would need to divide 125 by 4, getting 31.25. Now since the question needs 3/4 of 125, you multiply 31.25 by 3, which is 93.75. Now add 250, and 93.75. You get 343.75, or 343 3/4
