    I know the answer it is At 30 minutes, she took a 10 -minute break I just need an explanation on why that is the answer.

    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.

    That IS how to read the chart. If you post another chart, please supply YOUR interpretation.

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

    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. Copied a little from @tkhunny answer.

    Select a graph for the situation. You walk 1 mile to the bus stop, ride the express bus for 2 miles, and then walk another mile to your home.
