Recently, I decided to walk down an escalator of a tube station. I did some quick calculation in my mind. I found that if I walk down twenty " six steps, I require thirty seconds to reach the bottom. However, if I am able to step down thirty " four stairs, I would only require eighteen seconds to get to the bottom. If the time is measured from the moment the top step begins to descend to the time I step off the last step at the bottom, can you

• 26 steps 30 seconds and for 34 steps only 18 seconds left to reach botto.
  
  Means he covered 8 steps (i.e.34-26) in 12 (i.e 30-18)seconds
  The spped of the boy is 8 steps in 12 seconds
  after further simplyfy..2 steps in 3 seconds
  
  After 34 steps only 18 seconds, means 12 more steps are left
  Total Steps are 34+12 = 46

• 46 steps in the stair way
  
  If he walk 26 steps 30 seconds required
  for 34 steps only 18 seconds
  30*34-26*18/30-18=46

• d=s*t therefore s=d/t
  now the distance is height H of the escalator
  CASE 1: H-26/30
  CASE 2: H-34/18
  we have varies the distance keeping velocity constant therefore we can equate them
  h-26/30 = h-34/18
  h=46
