Question

an elevator descends into a mine shaft at the rate of 6 metre per minute if the distance starts from 20 m above the ground level how long will it take to reach - 340​

Answer 1

Answer: It takes 1 hour

Step-by-step explanation: Speed of the elevator - 6 metre/ min

Level from which the descend starts - 20 m above the ground

Level at which we have to reach - 340 m below the ground

We add both the numbers - 340 + 20 = 360 m

If we divide it by 6 so as to find the time: 360 ÷ 6 = 60 mins = 1 hour
