Question

Answer 1

Answer:

$14$ new signs are needed.

Step-by-step 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  $\frac{26}{0.5} -1=13-1=12$ signs.

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