Answer:
Option D is correct choice.
Explanation:
We are told that an architect's electronic blueprint of a building has a scale of 1 inch equals 12 feet.
To find actual distance between the floor on the first floor and the floor on the 15th floor we will multiply blueprint distance by 12.


Therefore, actual distance between the floor on the first floor and the floor on the 15th floor is 172.5 feet.
