Question

An elevator descends into a mine shaft at the rate of 6ml minute if the decent start from 10m above the ground level how long will it take to reach -350 m deep from the ground?​

Answer 1

Answer:

Distance is never negative.

so. total distance = 10 + 350

= 360 metres.

Distance covered in 1 minute = 6

hence, total time taken= 360/6

= 60 minutes or 1 hour

HOPE THIS HELPS!
