Question

An elevator descends into a mine shaft at the rate of 5 metre per minute. What will be it’s position after one hour. If it begins to descend from 15 metre above the ground level, what will be it’s position after 45 minutes. If the descent starts from 20 metre above the ground level. How long will it take to reach -370 metre

Answer 1

Hey

1 minute = 5 meter .So 1 hour (60mins)=60*5=300metres

It started 15 meters above the ground

So the present position under the ground =300-15=285 m .

So the elevator is 285 m under the ground
