Question

2. An elevator descends at the rate of 8 m/min. If the descent starts from 5 m above the ground level, how much time will it take to reach -475m? *

Answer 1

Answer:

60 min or 1Hr

Step-by-step explanation:

Speed = 8m/m

Total distance = 5m elevation + 475 m below ground = 480m

Time = distance/speed. 480/8=60min

Therefore, it will take 60 min or 1Hr to descend to -475m from 5m elevation from the ground.

Hope it helps ;-)
