The correct expression to show the sum of the diver's movements is:
-15 + 15
which simplifies to:
0
Therefore, the correct sum is 0.
To find the expression that shows the correct sum, we need to consider the diver's initial depth and the distance they swim upwards.
The diver starts at a depth of 15 feet below sea level, so we can represent this as -15 feet. When the diver swims up, they cover a distance of 15 feet in the upward direction. Thus, we can represent this as +15 feet.
To find the sum of these two distances, we add the two values together:
-15 feet + 15 feet
Simplifying this expression, we get:
-15 + 15 = 0
Therefore, the correct expression for the sum is 0, indicating that the diver returns to the surface at sea level.
