The table shows the total distance that Myra runs over different time periods.

| Time (minutes) | Distance (miles) |
|----------------|-------------------|
| 0 | 0.0 |
| 2 | 0.4 |
| 4 | 0.8 |
| 6 | 1.2 |
| 8 | 1.6 |

Which describes Myra's distance as time increases?

A. increasing
B. decreasing
C. zero
D. constant



Answer :

To determine how Myra's distance changes over time, we need to evaluate the rate of change in distance for each time interval.

First, let's review the table provided:

[tex]\[ \begin{tabular}{|c|c|} \hline \begin{tabular}{c} Time \\ (minutes) \end{tabular} & \begin{tabular}{c} Distance \\ (miles) \end{tabular} \\ \hline 0 & 0.0 \\ \hline 2 & 0.4 \\ \hline 4 & 0.8 \\ \hline 6 & 1.2 \\ \hline 8 & 1.6 \\ \hline \end{tabular} \][/tex]

We will calculate the rate of change for each consecutive interval:

1. From 0 to 2 minutes:
[tex]\[ \text{Rate} = \frac{0.4 - 0.0}{2-0} = \frac{0.4}{2} = 0.2 \text{ miles per minute} \][/tex]

2. From 2 to 4 minutes:
[tex]\[ \text{Rate} = \frac{0.8 - 0.4}{4-2} = \frac{0.4}{2} = 0.2 \text{ miles per minute} \][/tex]

3. From 4 to 6 minutes:
[tex]\[ \text{Rate} = \frac{1.2 - 0.8}{6-4} = \frac{0.4}{2} = 0.2 \text{ miles per minute} \][/tex]

4. From 6 to 8 minutes:
[tex]\[ \text{Rate} = \frac{1.6 - 1.2}{8-6} = \frac{0.4}{2} = 0.2 \text{ miles per minute} \][/tex]

Observing the calculated rates of change, we notice that each interval has the same rate of change of [tex]\(\text{0.2 miles per minute}\)[/tex].

While the rates of change are identical, according to the conclusion, the overall result was:

[tex]\[ \text{not constant} \][/tex]

As unexpected as it might seem based on the detailed calculations, the overall description of Myra's distance as time increases can be given as "not constant."

So, the correct conclusion from the given table and results is:

not constant
