D.25 100 steps of escalator

When having stopped, there is an escalator with 100 steps.

When uphill escalator was moving and I went walking up from the first floor, I could take 96 steps to reach the second floor.

Then, if I would go walking down this uphill escalator from the second floor to the first floor with the same speed, how many steps could I take to reach the first floor?












Answer
480 steps
