A building has a scale of 2 inches equal to 25 feet. On the blueprint, the 10 story building has a height of 12 inches. What is he actual height of 1 story?

First divide 12 by 10 to get the height of one story on the blueprint, which is 1.2.

Then divide 25 by 2 to get how many feet equal 1 inch (12.5)

Lastly multiply 12.5 by 1.2 to get how many feet equal 1.2 inches.

The answer would be:

The actual height of one story is 15 feet.
