1,000.
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).
1050
800 miles double 1 inch
400 x 2.5 = 1000 miles
2.5 x 400 = 1,000 miles
180 / 5 = 36 Therefore, working to the same scale factor, 180 miles would equal 36 inches.
1000
The scale of a map is decreased to show the representation of actual miles to the distance found on a map. If three fourths of an inch on a map was equal to 750 miles, an inch on the maps scale would equal 1,000 miles.
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.
2.5 x 400 = 1,000 miles
1,000 miles. 400+400=800+200=1,000
