Identify the scale factor if the length of a model train is 36 inches and the length of the engine itself is 24 feet?

The scale factor of the model train and the engine itself is 1/8 or 1:8.

Step-by-step explanation:

1. Let's check the information given to resolve the question:

Length of the model train = 36 inches

Length of the engine itself = 24 feet

2. Let's identify the scale factor:

Length of the model train = 36 inches = 36 /12 = 3 feet (12 inches = 1 foot)

Length of the model train = 3 feet

Scale factor = Length of the model train/Length of the engine itself

Scale factor = 3 feet / 24 feet = 1/8 (Dividing by 3 the numerator and the denominator and cancelling feet)

The scale factor of the model train and the engine itself is 1/8 or 1:8.
