Paulo's level is at an elevation of −104.87 meters relative to ground level. Which of the following is true about how much lower Paulo's level is than Vic's level?
A.
Paulo's level is 177.56 meters lower than Vic's level.
B.
Paulo's level is −177.56 meters lower than Vic's level.
C.
Paulo's level is −32.18 meters lower than Vic's level.
D.
Paulo's level is 32.18 meters lower than Vic's level.

Answer 1

To determine how much lower Paulo's level is than Vic's level, you need to calculate the difference between the two elevations.

Vic's level is at -72.69 meters, and Paulo's level is at -104.87 meters.

To find how much lower Paulo's level is than Vic's, we can calculate it as follows:

\[
\text{Difference} = \text{Paulo's level} - \text{Vic's level}
\]
\[
\text{Difference} = -104.87 - (-72.69)
\]
\[
\text{Difference} = -104.87 + 72.69
\]
\[
\text{Difference} = -32.18
\]

This means Paulo's level is -32.18 meters lower than Vic's level.

Thus, the correct answer is:
C. Paulo's level is −32.18 meters lower than Vic's level.
