Question

a diver 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

Answer 1

Answer:

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
