Question

An eagle is flying at an elevation 15 meters above the ground. A gyrfalcon is flying at an elevation 23 meters above the ground.

Write an inequality that correctly compares the elevations.

Which one of the following descriptions is correct?

The gyrfalcon is flying at a lower elevation than the eagle.
The eagle is flying at a lower elevation than the gyrfalcon.

Answer 1

The eagle is flying at a lower elevation than the gyrfalcon.

Explanation:

Let the eagle is flying at an elevation = x meter

and gyrfalcon is flying at an elevation = y meters

then difference in their elevations = (y-x) meters

1. Now inequality which compares the elevations will be

y - x > 23 - 15

y - x > 8

2. Since gyrfalcon is flying at 23 meters and eagle at 15 meters then the description which is correct.

The eagle is flying at a lower elevation than the gyrfalcon.

Answer 2

The correct answer for this question is this one: "The eagle is flying at a lower elevation than the gyrfalcon."

Among the following descriptions, this description is correct that says the eagle is flying at a lower elevation than the gyrfalcon.

Hope this helps answer your question and have a nice day ahead.
