Question

Wilbur landed his plane.

The plane's elevation relative to the ground (in meters) as a function of time (in seconds) is graphed.
graph
How long did it take the plane to land?

Answer 1

Answer:
`1,700\ seconds`

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
`8,500\ meters`. Based on the graph, each
`200\ seconds` the elevation of the plane decreases
`1,000\ meters.`

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:
`1,700\ seconds`
