Question

an elevator descends into a nine shaft at the rate of 6min/hour.if the descent start from 10m above the ground level,how long will it take to reach -350m.
​

Answer 1

Answer:

60 seconds or 1 minute

Step-by-step explanation:

Speed of elevator = 6m/minute

Distance that is to be travelled =

- 360( 10 m extra that is above the ground level)

As we know that Speed = distance/time

and we need to find out the time

so, time = distance/speed

= 360/6

= 60 seconds or 1 minute
