Question

Suppose a deep sea diver dives from the surface to 239 feet below the surface. He then dives down 16 m Which expression best represents the diver's situation.

A. 0+(-239) + (-16)
B. 0+ (-239) + 16
C. 0+239 +16
D. 0+239 + (-16)

Answer 1

The correct expression representing a diver diving 239 feet below the surface and then further down 16 meters is A. 0 + (-239) + (-16).

Step-by-step explanation:

A deep sea diver dives from the surface to 239 feet below the surface and then dives down another 16 meters. To represent the diver's situation, we need to convert meters to feet or vice versa, however, this is unnecessary for choosing the correct expression as we're looking for the operation between the numbers. Since both dives took the diver further away from the zero point (the surface), we are adding two negative displacements. Therefore, the correct expression is A. 0 + (-239) + (-16), which accounts for both descents below the surface in their respective units without a conversion.
