Final answer:
Using a scale factor of 1 to 8, the length of the model train caboose would be calculated by dividing the actual length of 32 feet by 8, resulting in a model that is 4 feet long. Option A
Step-by-step explanation:
If the actual caboose of the train measures 32 feet in length and the scale model is using a scale factor of 1 to 8, we can calculate the length of the model train by dividing the actual length by the scale factor. Using the scale factor means that every unit of measurement on the model represents 8 units on the actual train.
To find the model train's length, we do the following calculation:
32 feet (actual length) ÷ 8 (scale factor) = 4 feet (model length)
Therefore, the length of the model train will be 4 feet, which corresponds to option A.
