All you have to do is set up the proportions, then cross multiply.
Answer:
The way a proportion is set is as follows;
![\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%20%5C%20inch%7D%7B200%20%5C%20miles%20%7D%20%3D%20%5Cdfrac%7B4%20%5C%20inches%7D%7B%20Distance%20%5C%20from%20%5C%20Rio%20%5C%20de%20%5C%20Janeiro%20%5C%20to%20%5C%20San%20%5C%20Jose%7D)
The Distance from Rio de Janeiro and San Jose Costa Rica is then found as 800 miles
Step-by-step explanation:
The dimension of the distance between Rio de Janeiro and San Jose Costa Rica = 4 inches
The map scale = 1 inch to 200 miles
To figure out how many miles it is or the actual distance from Rio de Janeiro and San Jose Costa Rica, we have;
![\dfrac{1 \ inch}{200 \ miles } = \dfrac{4 \ inches}{ Distance \ from \ Rio \ de \ Janeiro \ to \ San \ Jose}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%20%5C%20inch%7D%7B200%20%5C%20miles%20%7D%20%3D%20%5Cdfrac%7B4%20%5C%20inches%7D%7B%20Distance%20%5C%20from%20%5C%20Rio%20%5C%20de%20%5C%20Janeiro%20%5C%20to%20%5C%20San%20%5C%20Jose%7D)
Therefore, we have;
(4 inches × 200 miles)/(1 inche) = Distance from Rio de Janeiro and San Jose Costa Rica
Which gives;
Distance from Rio de Janeiro and San Jose Costa Rica = 800 miles.
