a diver is 19 meters below the surface of the sea level. use an integer to represent how far the diver will need to travel to reach the surface

Position of Diver below sea level = 19 meters

In terms of integers

it will be represented as = - 19

The surface in terms of integers will be represented as = 0

To reach the surface we have to find additive inverse of - 19.

Additive inverse means, after adding two numbers we get Additive Identity.

Additive Identity of Integers = 0

So, Additive inverse of - 19 = + 19, because

⇒ - 19+19=0

So, Distance travel by Diver to reach the surface = + 19 meter

I believe that would be 19.
