To determine how many floors Alice traveled in the elevator to get from the underground parking garage to her hotel room on the 12th floor, we need to understand the numbering of the floors.
Assuming the underground parking garage starts at -1 below ground level, we have:
- The parking is at floor -1 (or perhaps lower).
- The hotel room is on the 12th floor.
Now, let's calculate the total number of floors Alice has to travel based on the starting point of her car in the garage:
-
If her car is parked on -1 (the first level below ground), she travels from -1 to 12:
- From -1 to 0: that is 1 floor.
- From 0 to 12: that is 12 floors.
- Total: 1 + 12 = 13 floors.
-
If her car is parked on -2, she would then travel:
- From -2 to 0: that is 2 floors.
- From 0 to 12: that is 12 floors.
- Total: 2 + 12 = 14 floors.
-
If her car is parked on -3, then:
- From -3 to 0: that is 3 floors.
- From 0 to 12: that is 12 floors.
- Total: 3 + 12 = 15 floors.
-
If her car is parked on -4, then:
- From -4 to 0: that is 4 floors.
- From 0 to 12: that is 12 floors.
- Total: 4 + 12 = 16 floors.
Thus, if we consider that she could be parking below ground level anywhere from -1 to -8, we can generalize:
If she was on -8, the total number of floors traveled would be:
- From -8 to 0: 8 floors.
- From 0 to 12: 12 floors.
- Total: 8 + 12 = 20 floors.
So, if we are to consider how far down Alice parked, the number of floors she would need to travel could vary significantly.
Since the question provides letters (A, B, C, D) with different values and we try to connect to her total travel going to floor 12:
- A -8 (not applicable)
- B 16: If Alice started on -4.
- C 8: Not applicable for the scenario.
- D -16 (not applicable)
Given the typical parking structures are from -1 to -4, it seems the correct choice relating to typical parking levels would be 16 floors if Alice parked on -4.
