From 2nd floor to 42nd floor, it moves 40 floors...
The distance that lift has to travel =
No. of floors ×height of each floor i.e. 40×6=240 m
Speed= Distance/ Time
3m/s=240m/t
t=240m/3m/s
t=80 s ( ans )

Answer:
time=20seconds
Step-by-step explanation:
From 2nd floor to 42nd floor, it moves 40 floors
the distance the lift has to travel will be no of floors * height of each floor i.e. 40*6=240 m
Speed= Distance/ Time
3m/s=240m/t
t=240m/3m/s
t=80 s
