Givens

Beginning level below sea level = -1260 feet

rate of descent = 5 feet per minute

Number of minutes = 12 minutes

Equation

Final level = initial level - rate * time Substitute givens into equation.

Solution

Final Level = - 1260 - 5*12

Final Level = - 1260 - 60

Final level = - 1329

Answer: - 1320 feet
