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