Answer 1

`14` new signs are needed.

Explanation:

Given: A
`26`-kilometer section of a highway is designated as a scenic byway. New signs will be placed at the beginning and end of this section and at every
`0.5` Km in between.

To find: How many new signs are needed?

Solution:

We have,

A
`26`-kilometer section of a highway is designated as a scenic byway.

New signs will be placed at the beginning and end of this section and at every
`0.5` Km in between.

So, there are
`2` signs placed, one at the beginning and one at the end.

Now, in between these
`2` signs there will be
`(26)/(0.5) -1=13-1=12` signs.

Hence, the total new signs that are needed is
`12+2=14`.
