Answer:
The model is 64.62 inches or 5.39 feet tall .
Step-by-step explanation:
Given:
Height of the Willis Tower in Chicago = 1,454 feet
Scale of the model = 2 inches : 45 feet height
To Find:
the height of the model = ?
Solution:
Let the height of the model be x
Then
[tex]\text{Height of the model} = \frac{ \text{Height of the Willis Tower in Chicago}}{\text{Scale in feet} }\times \text {Scale in inches}}[/tex]
On substituting the given values
Height of the model = [tex]\frac{1,454}{45} \times 2[/tex]
Height of the model =[tex]32.31 \times 2[/tex]
Height of the model = 64.62 inches
Converting into feet,
1 inch = 0.0833333 feet
so
[tex]64.62 = 0.083 \times 64.62 = 5.39[/tex] feet
