Avondale and Newtown are 45 miles apart. How many inches is this on a map with a scale 1inch=20miles?

I set up a proportion:
in/miles= 1/20=n/45 n= 2 and 1/4 in on this map

2 1/4 inches is correct.

1 inch = 20 miles
2 inches = 40 miles
1/4 inch = 5 miles

The distance between city A and city B is 200 miles. On a certain wall map, this is represented by a length of 1. 4 feet. On the map, how many feet would there be between city C and city D, two cities that are actually 500 miles apart?
