Basic math - If one inch= 400 miles;
2 inches = 800 miles +
1/2 inch=200 miles
Assuming you mean "two and a half inches"? The answer is 1000 miles
400 x 2.5 = 1000 miles
400 x 2.5= 1000 miles
1000
Since we know, 1 inch = 400 miles (on the map scale), then we can say 2.5 inches x 400 miles/inches = 1000 miles (The unit, 'inches' would cancel out) Where I got the 2.5 inches from is '2 1/2' 2 1/2 converted to a decimal number is 2.5
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).
If 400 miles is represented by 1 inch, then 2.5 inches represents 2.5 x 400 = 1000 miles.
There are 63,360,000 inches in 1000 miles. This is calculated by multiplying 1000 miles by 63,360 inches (1 mile = 63,360 inches).
The "scale" of a map is a proportionality constant between distances on the map and corresponding distances on the area the map represents. Call the unknown number of inches n. Then 1/2 = n/12, or n = 6.
1000.
1,000 inches is 0.02 miles.
If 1 inch equals 400 miles, then 2.5 inches would be equal to 1000 miles (2.5 inches x 400 miles/inch).
