Question

an underground mine elevator reaches a total depth of 99 meters. it descends 17% of the total distance every minute. how many meters below the ground is the elevator after 3 minutes. −67.32 meters −33.66 meters −16.83 meters −50.49 meters

Answer 1

Hello,

The correct answer is D) -50.49 meters

STEPS:

17% of total distance

it has a total distance of 99 ft

so it descends 17% of 99

17% of 99=0.17 times 99=16.83 feet per minute

3 minutes is 3 times 16.83 feet down or 50.49 down

Hope this helps!!!! :)

Answer 2

17% of 99 is 16.83. Since that's only the distance it goes in one minute we have to multiply that by 3. 16.83 × 3 = 50.49. Since the elevator is moving down then it will be negative. The answer will be -50.49 meters.
