An actual sit-down break would be characterized by the passage of time associated with no distance.  That would be a vertical line.  That seems to be hiding at the 4-mile mark.  The hint is in the problem statement where we are told that the entire hour was utilized.

Also, a more vertical slope might be considered a "break" -- walking, rather than running.

anonymous · Answer

well there you go. the line went flat at 30 min

tkhunny · Answer

Look for the passage of time with no distance.  That's a break.  It doesn't matter which direction it is pointed.

anonymous · Answer

is that the explanation

anonymous · Answer

An actual sit-down break would be characterized by the passage of time associated with no distance.  That would be a horizontal line. This is visible between 30 minutes and 40 minutes.
