Question

what is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swims 30 m below the surface

Answer 1

Answer:

130 meters

Step-by-step explanation:

We have to let the "surface of the ocea" be at 0 height.

So,

anything above surface has POSITIVE height

and anything below surface has NEGATIVE height

The albatross is 100 m above, so we can say its height is:

+100 meters

The shark is 30 m below, so we can say its height is:

-30 meters

The difference in height is thus:

100 - (-30) = 100 + 30 = 130 meters
