Question

A model of a skyscraper is made using a scale of 1 inch:75 feet. What is The height of the actual building if the height of the model is 19 2/5

Answer 1

I will assume that is 19 2/5 INCHES.

 

Set up a proportion with h = the actual height of the building.

 

19.4/h = 1/75

 

Now, solve for h after cross-multiplying:

 

h = 75 · 19.4 = 1455 feet.

 

That's a tall building!
