Question

question 1-78
at a scale of 1:2, a 12 - inch object would be represented by a line that is how long?
24 feet
6 inches
5 feet
24 inches

Explanation:

Step1: Recall scale - meaning

The scale 1:2 means the model (line) is half the size of the actual object.

Step2: Calculate line length

Let $x$ be the length of the line. We have the proportion $\frac{x}{12}=\frac{1}{2}$. Solving for $x$, we get $x = \frac{12\times1}{2}=6$ inches.

Answer:

B. 6 inches
