Distance between two places is 400 miles. The scale of the map is 1 in:200 miles. What is the distance between these two places in The Map

2 in

Step-by-step explanation:

if 200 miles = 1 in

400 miles = 400 miles x 1 in

                        200 miles

= 2in

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
