The numerical representation and final elevation of the fish relative to sea level are :

  • Final position = -13.52 + 7.8
  • Final position = - 5.72

Given the Parameters :

Initial depth of fish = - 13.52

Change in elevation of fish = 7.8 feets

Positions below sea level are represented as negative values (-) ;

Hence, initial position of fish = - 13.52

Change in position = Rise in depth of 7.8 feets

The numerical representation of the final position of the fish can be written thus :

  • Final position = Initial position + change in position

  • Final position = - 13.52 + 7.8

Hence, the final position of the fish will be :

  • Final position of fish = -13.52 + 7.8 = - 5.72
