Question

Which number below best represents a depth of two meters below the ground?

A. -2
B. 20
C. 2
D. -20

Answer 1

-2

Explanation:

We usually start measuring the height from the ground, so basically the positive direction is above the ground, for example 2 is the best number which represents 2m above the ground.

So the negative sign represents the depth below the ground.

Answer 2

The depth of two meters below the ground is best represented by the number -2, as negative numbers are used to indicate values below a reference point in mathematics.

To represent a depth of two meters below the ground, you're looking for a negative value because the depth is beneath the ground level. The correct option is:

A. -2

Here's a step-by-step explanation:

Depth below the ground level is conventionally indicated by negative values.

Among the given options, -2 is a negative number, indicating a depth.

The negative sign (-) denotes going below the ground level.

The number 2 represents the distance of two meters.

Therefore, -2 best represents a depth of two meters below the ground as per conventional representation where negative values denote below-ground depths.
