Answer:

Here we have the relation:

m = 140*h

Where m is the distance in miles, and h is time in hours.

And we want to complete a table like:

\left[\begin{array}{ccc}in, h&out, m\\&\\&\\&\\&\end{array}\right]

The way to complete this, is to evaluate the function:

m = 140*h

in different values of h, and then record both values of h and m in the table.

Let's use values of h that increase by 0.5, then:

if h = 0.5

m = 140*0.5 = 70

We have the pair: h = 0.5,  m = 70

if h = 1

m = 140*1 = 140

We have the pair: h = 1, m = 140

if h = 1.5

m = 140*1.5 = 210

Then we have the pair h = 1.5, m = 210

if h = 2

m = 140*2 = 280

We have the pair: h = 2, m = 280

Now we can complete the table, and it will be:

\left[\begin{array}{ccc}in, h&out, m\\0.5&70\\1&140\\1.5&210\\2&280\end{array}\right]

Varvara68 [4.7K]

Answer:

2 \frac{2}{9}

Step-by-step explanation:

First, we will turn 5 2/5 into an improper fraction:

5 * 5 = 25 + 2 = 27/5

So they worked for 27/5 days.

We want to divide the days worked by the distance to get the unit rate of distance per day:

\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}

So our answer is 2 \frac{2}{9}

      Hope this helps, have a great day! :D
