\(\text{The horizontal section of the graph indicates Elvis’ distance}\)

\(\text{from home is not changing and he is resting.}\)

\(\text{The slope before and after the rest break is the same, so Elvis’}\)

\(\text{speed of travel was the same before and after the rest.}\)

 

\(\therefore\ \text{Elvis walked, rested then walked.}\)

 
\(\Rightarrow D\)
