Question

a model car has been made using a scale factor if 1.5 inches:3 feet. If the actual car is 13.75 feet long, what is the length of the model?

Answer 1

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.

Answer 2

well... that's to hard for me sadly when I learned a lot how to do that, i'll give you this though when you going from bigger to smaller you divide, when you going smaller to bigger you times.

Good luck though ;)
