Adiver is 19 meters below the surface of the water use an integer to represent how far the diver will need to travel to reach the surface

The diver need to travel 19 meter up to reach the surface

Step-by-step explanation:

* Lets explain how to solve the problem

- For any starting point the position at it is zero

- If the moving from the starting point is vertically, then the distance

 below the starting point is negative and above the starting point

 is positive

- If the moving from the starting point is horizontally, then the

 distance left to the starting point is negative and right to the

 starting point is positive

* Lets solve the problem

- A diver is 19 meters below the surface of the water

- Assume that the surface of the water is the zero position

∵ The diver is 19 meter below the surface of the water

∴ The diver is at the position -19

- The diver need to travel 19 meters to reach the surface of the water

∵ -19 + 19 = 0

∴ The diver need to travel 19 meter up to reach the surface

dont trust me im no expert these losers made me fail a test bro this sucks
