820 inches
400 x 2.5 = 1000 miles
800 miles double 1 inch
400 x 2.5= 1000 miles
1000
2.5 x 400 = 1,000 miles
20"=8,000 1.5"=600 21.5 inches=8,600
1,000 miles. 400+400=800+200=1,000
One-and-a-half times 400
Assuming you mean "two and a half inches"? The answer is 1000 miles
That depends entirely on what the scale of the map is.
If 400 miles is represented by 1 inch, then 2.5 inches represents 2.5 x 400 = 1000 miles.
1in. = 4 2in. = 8 half of 4 = 2 8+2=10 so two and a half is equal to 1000 miles
