Question

i still cant figure this one out, can someone please help??

Answer 1

B

Answer 2

map is in cem , so all denom should be in CM to match the proportions correctly

Answer 3

all miles are at the bottom as denominators, which would include the ACTUAL distance Miles

Answer 4

So the proportion is gonna be based off of this:

map
---
actual

If on the map, 3 cm =to 21 miles then the first fraction would be set up like this

3cm
----
21miles

And then the question asks you how much miles in real life would it be if there are 5cm apart. So the second fraction is

5cm
----
x

x because you don't know how many miles there are. Then you set up the proportion

3 5
-- = --
21 x

So the answer is....?
