Step-by-step explanation:
On moving from 2nd floor to 42th floor
there are 40 floors in between.
If the elevation speed of the elevator is 3 m/s then
Time taken by each floor to move to the next floor = 6/3
=2 s
Therefore,
Total time taken = No. of floors × Time taken per floor
= 40 × 2
=80 seconds
