Answer:
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
