# A multistorey bui

We have

Since, it is given that the man starts from 50 m from the ground.

Distance of the man from the ground = 50 m

There are about 3 floors in the basement.

The man has to reach the 2nd floor of the basement and it is given that, distance between floors is 5 m.

So, distance between ground and 1st floor of basement = 5 m

And distance between 1st floor and 2nd floor of basement = 5 m

Distance between ground and 2nd floor of basement = 5 + 5

Distance between ground and 2nd floor of basement = 10 m

Total distance between man and 2nd floor of the basement is given by,

Total distance = Distance between man and ground + Distance between ground and 2nd floor basement

Total distance = 50 + 10

Total distance = 60 m

But, the speed of lift = 1 m/s

We need to find the time taken by the lift to reach 60 m at speed, 1 m/s.

Since,

Time = 60 s

Thus, it takes 60 seconds or 1 minute to reach at 2nd floor of the basement.
