How deep is the shark now?

What integer represents the shark’s new depth?

A. -235

Final answer:

The shark, initially at a depth of -300 feet, moves 65 feet closer to the surface.

Explanation:

The shark's initial depth is represented by the integer -300, as it is located 300 feet below sea level. When the shark moves 65 feet closer to the surface, it ascends, which can be represented mathematically as adding +65 to -300, as positive numbers represent movement towards the surface in this context. Therefore, to find the new depth of the shark, we perform the operation: -300 + 65 = -235. So, the shark's new depth is now -235 feet, this integer being a representation of 235 feet below sea level.

With the shark moving 65 feet closer to the surface from its initial depth of 300 feet below sea level, the shark's new depth is now at -235 feet deep. Despite moving closer to the surface, the shark remains below sea level.

Integer operations are important in scenarios like this where we need to calculate changes in depth or position. By understanding how to add and subtract integers, we can accurately determine the new position of objects in different environments.

It's fascinating to see how mathematical concepts can be applied to real-life situations, such as tracking the movement of marine animals like sharks. By practicing integer operations, we can enhance our problem-solving skills and make sense of the world around us.
