Question

Surveying: A unit of measure sometimes used in surveying is the link; 1 link is about 8 inches. About how many links are there in 7 feet? Do not round your answer.There are ? links in 7 feet.

Answer 1

Let's start by converting foot to inch. 1 foot has 12 inches, so if we have 7 feet, we will twice as many inches, so we have

7 * 12 inches = 84 inches.

We 1 link has 8 inches, it means that 1 inch has 1/8 link.

Thus, if we have 84 inches, we will have 1/8 of that as links, so we have

`84\cdot(1)/(8)\, links=10.5\, links`

Thus, there are 10.5 links in 7 feet.
