Question

A model skyscraper is made with a scale of 1 inch to 75 feet. What is the height of the model if the height of the building is 1,395 feet?

Answer 1

18.6 inches

Explanation:

As we have the scale between the model and the real skyscraper, and we also have the height of the real building, to find the height of the model we just need to use a rule of three:

1 inch -> 75 feet

x inches -> 1395 feet

x*75 = 1*1395

x = 1395 / 75

x = 18.6 inches

The height of the model skyscraper is 18.6 inches.
