Question

A scale model of a train engine is 1 inches

long. An engine on a real train is 28 feet long.
If a freight car on the model train is 2 inch long,
what is the actual size of the freight car on the
real train?

Answer 1

The actual size of the freight car on the real train is 56 feet

Explanation:

1. Let's review the information given to us to answer the question correctly:

Scale model of the train engine length = 1 inch

Real length of the train engine = 28 feet

Scale model of the freight car = 2 inches

2. What is the actual size of the freight car on the real train?

We will use the Rule of Three Simple to answer this question, this way:

Actual size Scale model

28 feet 1 inch

x 2 inches

Actual size of the freight car on the real train * 1 = 28 * 2

Actual size of the freight car on the real train = 56 feet

The actual size of the freight car on the real train is 56 feet
