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

Total distance of the elevator = 99m

Descending distance every minute = 99*17/100
= 16.83 m
Descending distance in 3 minutes = (16.83*3)
= 50.49 m

So the answer is 50.49 m
