It depends on the scale to which the map has been drawn. Not all maps are the same scale.
180 / 5 = 36 Therefore, working to the same scale factor, 180 miles would equal 36 inches.
800 miles double 1 inch
400 x 2.5= 1000 miles
2.5 x 400 = 1,000 miles
1000
That depends entirely on what the scale of the map is.
5 inches will equal 10 miles if the scale is 1 inch equals 2 miles
820 inches
180 / 5 = 36 Therefore, working to the same scale factor, 180 miles would equal 36 inches.
Assuming you mean "two and a half inches"? The answer is 1000 miles
One inch would equal 50 miles so 5 inches would equal 250 miles 250 Miles
20"=8,000 1.5"=600 21.5 inches=8,600
1050
400 x 2.5 = 1000 miles
800 miles double 1 inch
400 x 2.5= 1000 miles
2.5 x 400 = 1,000 miles
