Answer 1

Hey Friend, Your answer is given below.

Each floor height is 5m.
Then, 50m abve the ground is the 10th floor.
We have to go to the 2nd floor.
2nd floor is at an height of 10m.
To go from 50m above the ground to 10m above the ground, the distance we have to cover is (50-10)m=40m.
Speed of the lift=1m per second.
Then, the time taken to go from 50m above the ground to 2nd floor=40×1 second(s)=4 seconds.
Hence, if the man starts a lift from 50m above the ground, then he will reach the 2nd floor of the basement in 40 seconds.

Hope it helps.
