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.
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 !
If 1 inch equals 400 miles on the map, then 2.5 inches on the map would equal 1000 miles in real life. This is calculated by multiplying the scale factor (1 inch equals 400 miles) by the distance on the map (2.5 inches).
It would be 360 miles.
On the scale 1 inch:2 miles. 12 miles would be 6 inches
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.
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.
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?
1,000.
