It takes you 47 seconds to walk from the first (ground) floor of a building to the third floor.

How long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height) ?

Answer: 117.5 seconds

Step-by-step explanation:

Given : It takes you 47 seconds to walk from the first (ground) floor of a building to the third floor.

Since from first floor to third, a person need to pass two levels of staircase.

We assume that the person walk at the same pace and the height of all floors are same.

The time taken to pass each level = (Time taken to pass 2 levels) : 2

= (47 seconds) : (2) = 23.5 seconds

Also, the from first floor to sixth floor, a person need to pass 5 levels of staircase.

Then, the time taken to pass each level = 5 x (Time taken to pass one level)

= 5 x 23.5 = 117.5 seconds

Hence, it will take 117.5 seconds to walk from the first floor to the sixth floor.
