Answer:
Elevator take 1 hour to reach -350 m.
Step-by-step explanation:
Given:
Speed of the elevator = 6 m/min
Elevator starts 10 m above ground level.
Elevator travel to -350 m.
⇒ Elevator travel to 350 m below ground level.
To find: Time taken by elevator to reach 350 m below ground level.
Total distance traveled by elevator = 350 + 10 = 360 m
Time taken to travel 360 m = 360/6 = 60 minutes = 1 hour.
Therefore, Elevator take 1 hour to reach -350 m.
