Answer: [tex]1,700\ seconds[/tex]
Step-by-step explanation:
Observe the graph provided in the exercise.
The y-axis represents the plane's elevation in meters and the x-axis represents the time in seconds.
Notice that at 0 seconds the elevation of the plane is [tex]8,500\ meters[/tex]. Based on the graph, each [tex]200\ seconds[/tex] the elevation of the plane decreases [tex]1,000\ meters.[/tex]
The plane lands when the elevation is 0 meters and this happens when the line shown in the graph intersects the x-axis.
Therefore, the time took the plane to land is:[tex]1,700\ seconds[/tex]
