1. Question :

   • An Elevator descends into a mine shaft at the rate of 6 meters per minute. If descends starts from 10 meters above ground level, how long will it take to reach— 350meters.

   Let’s Start :

   • Considering an elevator to be at constant speed and the destination to be 350 meters below ground level.

   • The elevator has to travel 10 meter till the ground then 350 meters more.

   so the total distance travelled is = 360 meters

   • If the elevator speed is 6 meters/minute

   Then :

   ➜ Time = distance/speed

   ➜ 360/6

   ➜ 60 minutes

   ➜ 1 hour.

   So, the elevator would take 1 hour to reach its destination.
