Question

a diver is 19 made it below the surface of the water use an integer to represent how far the diver would need to travel to reach to Surfer

Answer 1

If the diver is 19 meters below the surface, we can represent the depth as a one-dimension measure, where the surface has a value of 0.

Then, if he is 19 below the surface, he is at x=-19.

He has to travel from x=-19 to the surface (x=0), then the difference is:

Surface - Actual Position = 0 - (-19) = 19

He need to travel 19 meters towards the surface.
