Every day, you take the elevator from basement parking lot that is at level -3. You live on the 23rd floor and the elevator takes two seconds per level. How long does your daily elevator ride take?

Level "-3" indicates that parking is underground.

So, the levels are: -3, -2, -1, 0, 1, 2, 3......23

Total levels: 27

Time taken for each level = 2 seconds

Total time = 27 levels × (2 seconds / level)

= 54 seconds
