Question

In one hour, an elevator travels up five floors, down 2 floors, up 8 floors, down 6 floors, up 11 floors, and down 14 floors. If the elevator started on the seventh floor, on which floor is it now?

Answer 1

After calculating each movement of the elevator, which includes going up and down a number of floors from the starting point of the 7th floor, the elevator ends up on the 9th floor.

Step-by-step explanation:

The student is asking about the final floor of the service elevator after a series of movements starting from the seventh floor. To solve this, we will perform a series of additions and subtractions based on the elevator's movements:

• Start on the 7th floor.
• Go up 5 floors: 7 + 5 = 12.
• Go down 2 floors: 12 - 2 = 10.
• Go up 8 floors: 10 + 8 = 18.
• Go down 6 floors: 18 - 6 = 12.
• Go up 11 floors: 12 + 11 = 23.
• Go down 14 floors: 23 - 14 = 9.

After all these movements, the elevator would be on the 9th floor.
