That would be a world map. To give you a reference, the US from east coast to west coast is about 3000 miles. So the length on a map of the US would be about 2 inches.
1 inch equals 100 miles would be the smaller scale, as 1 inch on the map would be a plot of 100 miles of terrain, as opposed to 200 miles of terrain.
To answer that question, I would need the context which details a scale. If one inch on a scale equals 14 miles, that scale remains the same. So two inches (which equals 1 times 2) would translate into 28 miles (because 14 times 2 is 28). The same would hold true for 400 miles. If one inch equals 400 miles, two inches equals 800 miles, and three inches equals 1200 miles.
5 inches will equal 10 miles if the scale is 1 inch equals 2 miles
You should probably finish your question.
On that scale... 6 inches !
1,000 miles
It would be 360 miles.
On the scale 1 inch:2 miles. 12 miles would be 6 inches
On a map.
200 because it would have more miles in the inch than 100 miles.
A map with 2000 miles per inch would cram more things into the inch than one that uses 1 inch for 1000 miles. So the map with the scale of 1 inch for 1000 miles would show more detail.
Remember it this way: If you had two model submarines of the same boat, one was 1:50 scale and one was 1:200 scale, which model would be larger?
