An elevator is 25 m below the ground level and it ascends at the rate of `5m/min` . Find the time takenby it to reach 50 m above the ground.

An elevator is 25m below the ground level and it ascends at the rate of 5(m)/(min). Find the time takenby it to reach 50m above the ground.

An elevator descends into a mine shaft at the rate of 5m/min. If the descent starts from 15m above the ground level, how long will it take to reach -250m.

An elevator descends into a mine shaft at the rate of 6 m//min . If the descent starts frm 10m above the ground level, how long will it take to reach -350 m.

An elevator descends into a mine shaft at the rate of 6 m/min. If the descent starts from 20 m above the ground level, how long will it take to reach 370 m ?
