Answer:
18 1/4
Step-by-step explanation:
To find how long it took Amy to run her fastest and slowest mile combined, we add the two values.

Hint #44 / 5
\begin{aligned} 9\dfrac24+8\dfrac34&=(8+9)+\left(\dfrac{2}{4}+\dfrac{3}{4} \right)\\\\ &= 17+\dfrac{5}{4}\\\\ &=17+1\dfrac{1}{4}\\\\ &=18\dfrac{1}{4} \end{aligned}

Disclaimer: The given question was incomplete, with the data missing. The complete question can be seen in the picture attached.
Analyzing and interpreting the given data, we can say that Amy took 18 1/4 minutes in total to run her slowest and fastest mile combined.
The process of attributing meaning to the acquired data and deciding the conclusions, relevance, and consequences of the results is known as data analysis and interpretation.
We are given a data set, representing the time taken by Amy to run each mile while running 8 miles, nearest to 1/4th of a minute.
We are asked to find how long did it take Amy to run her slowest and fastest mile combined.
Analyzing the data, we can say that her slowest mile will be the one for which she took the maximum time, that is, 9 2/4 minutes. Whereas her fastest mile will be the one with the minimum time, that is, 8 3/4 minutes.
We are asked to tell the combined time for her slowest and the fastest mile, so we add times for both, to get
Combined time = 9 2/4 + 8 3/4
or, Combined time = 38/4 + 35/4
or, Combined time = 73/4
or, Combined time = 18 1/4.
∴ Analyzing and interpreting the given data, we can say that Amy took 18 1/4 minutes in total to run her slowest and fastest mile combined.
