A multistorey building has 25 floors above the ground level each of height 5m. It also has 3 floors in the basement each of height 5m. A lift in building moves at a rate of 1m/s. If a man starts from 50m above the ground, how long will it take him to reach at 2nd floor of basement?
Answers (2)
Given: Height of each floor = 5 m
given that man starts from 50 m above ground level and reaches to 2nd floor of the basement.
The total distance covered by him = 50+10 m =60 m
Rate of moving = 1 m/s
Time is taken by lift reach at 2nd floor of basement = 60 seconds = 1 minute
