Answer:
A. -3.84 meters
Step-by-step explanation:
Given:
A penguin can dive 2% of the total depth every 1 second.
Total depth = 48 meters.
Now we have to find 2% of 48.
=
=
= 0.96 meter
So, the penguin dives -0.96 meters per seconds down the water.
The negative sign represents below the surface of the water.
The total depth of the penguin after 4 seconds = 4 times -0.96
= -3.84 meters
Therefore, the answer is A. -3.84 meters
