Question

the length of the scale drawing of the car is 3 inches. find the length of the actual car in feet. start by finding the length of the actual car in inches. scale: 1 to 48

Explanation:

Step1: Use scale - factor relationship

The scale is 1 to 48, which means 1 inch on the drawing represents 48 inches in real - life. If the scale drawing length is 3 inches, then the actual length in inches is found by multiplying the scale - drawing length by the scale factor. So, the actual length in inches $L_{inches}=3\times48 = 144$ inches.

Step2: Convert inches to feet

Since 1 foot = 12 inches, to convert the length from inches to feet, we divide the length in inches by 12. So, the actual length in feet $L_{feet}=\frac{144}{12}=12$ feet.

Answer:

12
