The final distance traveled by the elevator is 60m and moved 36m (option B).
How to calculate the total distance traveled by the elevator?
To calculate the total distance traveled by the elevator, we must take into account that each floor is equivalent to a distance of 3 meters.
So we need to multiply the number of floors he travels on each trip and multiply it by 3 to find the distance he traveled.
3m × 7 = 21m
3m × 4 = 12m
3m × 9 = 27m
To know the total distance traveled by the elevator, we must add the meters traveled in each displacement:
21m + 12m + 27m = 60m
On the other hand, to know the displacement that the elevator made from its initial position to its final position, we multiply 3 by the number of floors that there is a difference between its initial position and its final position.
3m × 12 = 36m
According to the above, it can be inferred that the correct answer is B. Because the elevator traveled a total of 60m and moved 36m.
