Question

A bird flies at an elevation of 10 feet. Which is closer to sea level than the bird?

Answer 1

Answer:

B. A boy swimming at an elevation of –3 feet.

Step-by-step explanation:

We have been given that a bird flies at an elevation of 10 feet. We are asked to choose the elevation that is closer to sea level than the bird.

Let us find absolute value of each elevation.

A. A fish swimming at an elevation of –18 feet.

$|-18|=18$

The fish is 18 feet away from sea level.

B. A boy swimming at an elevation of –3 feet.

$|-3|=3$

The boy is 3 feet away from sea level.

C. A kite flying at an elevation of 30 feet.

$|30|=30$

The kite is 30 feet away from sea level.

D. A bird sitting in a tree at an elevation of 12 feet

$|12|=12$

The bird is 12 feet away from sea level.

Since the distance between the boy swimming and sea level is less than other distances, therefore, the boy is closer to sea level than the bird.

Answer 2

A boy swimming at an elevation of 3 feet below sea level. This is the answer because the boy is only 3 feet away from sea level while the bird is 10 feet away form sea level.
