Question

: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?​

Answer 1

Answer:

1 minute (60 seconds)

Step-by-step explanation:

50 m above is 10th floor and since the lift moves 1 m per second it will take it 50 seconds to reach ground level and as 2 floors= 10 m and 10 seconds for 10 meter 50 + 10 equals 60 seconds
