Answer:
The build 2
kilometers each day
Step-by-step explanation:
<em>Set up an equation</em>
<em>The road is 12 kilometers long and it was worked on for 5
days.</em>
<em>So, to set up the equation, divide 12 by 5
</em>
<em>Make 5
into an improper fraction</em>
<em>Multiply 5 by 5, then add 2</em>
<em>
</em>
<em>You can't divide a number by a fraction, so you kcf (keep it, change it, flip it)</em>
<em>So keep the 12, change the division to multiplication, flip
</em>
12 x
<em>Multiply straight across</em>
x
= 
<em>Simplify </em>
=
<em> </em><em>The top and the bottom both have 3 in common</em>
<em>Then make
into a mixed number</em>
2
<em>9 goes into 20 2 times and has a remainder of 2</em>
