Marcus dives from the surface of the ocean to a reef 18 m below sea level what integer represents marcus's location relative to the surface how far does marcos have to go to return to the surface

The integer which represents Marcus's location relative to the surface is -18 M.

Marcos have to go 18 M to return to the surface.

Step-by-step explanation:

Consider the provided information.

Integers are the number that do not contain any decimal or fraction. They contains positive counting number, negative counting numbers and zero.

For example:{...-3,-2,-1,0,1,2,3...}

We need to use integers to represents Marcus's location.

The statements is related with sea level.

Let say the sea level is at the zero, if a point is below sea level then we will indicate it by placing a negative sign in the front of the number and if it is above the sea level then we will indicate it by placing a positive sign or no sign in the front of the number.

Marcus dives from the surface of the ocean to a reef 18 M below sea level

Which can be written as: -18 M (In integer)

Now we need to find how far does Marcos have to go to return to the surface

As we assumed the surface of the ocean is at the zero, so we need to add an integer in -18 that makes the integer 0.

Thus the number is 18 which makes -18 equals to 0.

Hence, Marcos have to go 18 M to return to the surface.
