Assuming you mean "two and a half inches"? The answer is 1000 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 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
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
( 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
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).
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
800 miles double 1 inch
400 x 2.5 = 1000 miles
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
