We have to find the scale factor of 8 inches = 200miles.
To find the scale factor first we have to make the units equal.
Here we will convert miles to inches.
We know that 1 mile = 5280 ft.
And 1 ft = 12 inches.
So we can write that 1 mile =
inches = 63360 inches
Here 200 miles given.
So 200 miles =
inches.
= 12672000 inches.
Now the scale factor of 8 in = 200 mi is
8 in = 12672000 in
1 in =

1 in = 1584000 in
So the scale factor is 1:1584000.
We have got the required answer.
