To determine how far the caterpillar can crawl in 1 minute, we can set up a proportion based on the distance it covers in a shorter time period.
The caterpillar crawls \( \frac{1}{2} \) inch in \( \frac{1}{4} \) minute.
To find the distance it would crawl in 1 minute, we can multiply the distance it covers in \( \frac{1}{4} \) minute by the number of such intervals in 1 minute:
\[ \text{Distance in 1 minute} = \frac{1}{2} \text{ inch} \times 4 = 2 \text{ inches} \]
So, the caterpillar can crawl 2 inches in one minute.
