Assuming you mean "two and a half inches"? The answer is 1000 miles
It would take 6 inches to show 12 miles.
1 375 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.
The distance can be measured with any ruler and compared to the scale on the map. For example 1/4inch equal 5miles, and if you measure the route and it equals 1 1/2 inches. 1 1/2 = 6/4, 6*5= 30miles
The scale is 83 1/3 miles per inch, times 34.5 inches is 2875 miles.Using decimals would introduce a slight error, so what you may want to do instead is assume a scale 1 inch = 250 miles, times 34.5 is 8625, and then divide by 3 for your actual scale. 8625/3 = 2875
( inches is three times 3 inches, so three times 100 miles is 300 miles
5 inches will equal 10 miles if the scale is 1 inch equals 2 miles
180 / 5 = 36 Therefore, working to the same scale factor, 180 miles would equal 36 inches.
Assuming a scale of 800 miles to every one inch, 3.25 inches will equal 3.25 x 800 = 2600 miles.
1050
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.
400 x 2.5 = 1000 miles
800 miles double 1 inch
1000
2.5 x 400 = 1,000 miles
when 1 inch = 400 miles then 2.5 inches = 2.5 x 400 = 1,000 miles
On that scale... 6 inches !
2.5 x 400 = 1,000 miles
