A scale model of a tower is 24 inches tall and 18 inches wide. If the height of the actual tower is 60 feet, what is its width?

18 ft

80 ft

24 ft

45 ft

We can set up a proportion to solve this problem as follows:

height of the model/width of the model = height of the actual/width of the actual

24/18=60/x

Cross multiply,

24x=18*60

24x=1080

x=45 ft.

Therefore the answer is 45 ft.
