9. Oliver is 8 feet above the surface of the water. There is a school of fish
10 feet below the surface. A ledge with some seashells is 18 feet below
the surface, and even deeper there is a shipwreck 32 feet below
the surface.

a. How many feet will Oliver have to travel to get to the seashells?

b. How much deeper is the shipwreck than the school of fish?

Okay so if you draw a line graph going vertical and you number it 1-32 ( this is if you have to show work ) a is a 11 feet deeper and b is 23 feet deeper

Answer:

Oliver is 8 feet above the surface of the water.

There is a school of fish 10 feet below the surface.

A ledge with some seashells is 18 feet below the surface.

There is a shipwreck 32 feet below the surface.

Part A:

Assuming that all given depths are from surface level.

Now Oliver will go down 8 feet to reach the surface of water, then again 18 feet below that to get to the seashells.

So, total he will go down [tex]8+18=26[/tex]feet

Part B:

[tex]10-32=-22[/tex] feet

The shipwreck is 22 feet more deeper than the school of fish when measured from surface level.
