A bird can fly at an elevation of 6400 meters. A fish can swim at a depth of 500 meters. What is the difference between the birds elevation and the fish's depth

The depth can be represented as

d = b - f where

d = depth

b = bird height

f = fish depth

d = 6400 - ( - 500)

d = 6400 + 500

d = 6900 m

Answer: The difference in the elevation and depth of the bird and fish is 6900 m

5900 is the answer because
