Question

An elevator descends into a mine shaft at the rate of 6 metres per minute. If the descend

starts from 10 m above the ground level, how long will it take to reach -350 m.​

Answer 1

Answer:

1 hour

Step-by-step explanation:

Rate of descent = 6m/min

Starting point = 10m above ground level

Ending point = 350m below ground level

Total distance = 10 + 350 = 360m

Total time taken = 360 ÷ 6 = 60mins

Ans) It would take 1 hour for the elevator to reach -350m.
