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
. Based on the graph, each 
the elevation of the plane decreases 
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:
