A whale is swimming at an altitude of −42
meters and then ascends 20 meters to the surface. What is the altitude at the surface of the water?
To find the altitude at the surface of the water, we need to add the initial altitude of the whale to the distance it ascends.
Initial altitude = -42 meters
Distance ascended = 20 meters
-42 meters + 20 meters = -22 meters
Therefore, the altitude at the surface of the water is -22 meters.
To find the altitude at the surface of the water, we need to add the ascent of the whale to its initial altitude.
Initial altitude of the whale = -42 meters
Ascent of the whale = 20 meters
Thus, the altitude of the whale at the surface of the water is:
-42 meters + 20 meters = -22 meters
Therefore, the altitude at the surface of the water is -22 meters.
