Question

The scale of a model train is 1 1 inch to 13.5 13.5 feet. One of the cars of the model train is 5 5 inches long. What is the length, in feet, of the actual train car?

Answer 1

74.25feet

Explanation:

Given the scale of a model train expressed as;

1in = 13.5feet

We are to express length of 5.5in in feet

5.5in = x

Divide both expressions

1/5.5 = 13.5/x

Cross multiply

1×x = 5.5× 13.5

x = 74.25feet

Hence the actual length of the car in feet is 74.25feet
