To find the scale of the drawing, we need to determine how many inches in the drawing represent each foot in reality.
Given that the basketball goal is 15 ft tall in reality and its representation in the drawing is 3 inches, we can set up a proportion:
15 ft = 3 inches
To solve for the scale, we need to find out how many inches represent one foot. We can set up the proportion as follows:
x inches = 1 ft
Now we can cross-multiply and solve for x:
15 ft * x inches = 3 inches * 1 ft
15x = 3
Divide both sides of the equation by 15:
x = 3/15
Simplifying, we find:
x = 1/5
Therefore, the scale of the drawing is 1 inch represents 5 feet.
