The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)

What is equation?

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.

Whale swims 80 ft below so it be a negative number.

Whale then swims up 40 ft so would be adding .

When the whale is 120 ft below the water's surface so it be a negative number.

-80+ 40 = -120

Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120
