Answer:

28 minutes

Explanation:

Hello!

The black line represents Lynn's speed throughout the course of the run, while the blue line represents Kael's run throughout the run.

The y-values of the graph represent the speed of each person, while the x-values represent the time.

To find out how long Lynn was running faster than Kael, we can find the range of the x-values when the black line is ABOVE the blue line.

The first point when it was above the blue line is when x is at 12. The final point is when x is at 40.

Subtract:

  • 40 - 12
  • 28

Since the units are minutes, Lynn was faster than Kael for 28 minutes.

Answer: The last option, 28 minutes

Explanation:

See attached for my work. If you are color blind let me know, I color-coded where I "pulled" numbers from.

To answer this problem, we can look at the graph. We need to see for how long the black line is above the blue.
