Final answer:
To find the length of the model car, set up a proportion and cross multiply.
Step-by-step explanation:
To find the length of the model car, we need to use the scale factor given. The scale factor is 1.5 inches:3 feet. This means that for every 1.5 inches in the model, there are 3 feet in the actual car.
Given that the actual car is 13.75 feet long, we can set up a proportion:
1.5 inches / 3 feet = X inches / 13.75 feet
Cross multiplying, we get:
1.5 inches * 13.75 feet = 3 feet * X inches
Simplifying, we find that the length of the model car is approximately 6.88 inches.
