Aperson walks up a stationary eioalatorin 90 sec. the escalator moves with the person, standing on it, it wil take 1 minute reach the lop from ground How much time would take him up the moving escalator? (A) 24 sec 36 sec ID 40 sec

Explanation / Answer

Here ,

let the distance is d

speed of the eascaltor is v

speed of person is u

NOw , for the stationay eascaltor

u = d/90

Now, for the moving eascaltor

v = d/60

Now, for person with moving eascaltor

time taken = d/(u + v)

time taken = d/(d/90 + d/60)

time taken = 36 s

the time taken is 36 s
