Answer:
Explanation:
The length of the subway is 900 miles.
So if 1 inch is 45....we want to find it for 900 miles
900/45 = 20
So it will be 20 inches for 900 miles
Check by using ratio
1 : 45
2 : 90
3 : 135
4 : 180
5 : 225
6 : 270
7 : 315
8 : 360
9 : 405
10 : 450
11 : 495
12 : 540
13 : 585
14 : 630
15 : 675
16 : 720
17 : 765
18 : 810
19 : 855
20 : 900
1 - 20 = inches
45 - 900 = miles
So for 900 miles, it will be 20 inches long
