Final answer:
You are 32 feet underwater.
Step-by-step explanation:
To determine how far you are underwater, we need to calculate the total change in depth. If you start at 12 feet underwater, then descend another 13 feet, your total descent is 12 + 13 = 25 feet. After 2 minutes, you ascend 19 feet, so your total change in depth is -19 feet (negative because you're going up).
To find the final depth, we add the total change in depth to your initial depth:
Final depth = Initial depth + Total change in depth
Final depth = 12 - 25 + (-19) = -32 feet
So, you are 32 feet underwater.
