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.

a
−67.32 meters

b
−33.66 meters

c
−16.83 meters

d
−50.49 meters

Answer 1

17% of 99 =16.83m

then we multiply 16.83 by 3 = 50.49m

We are going downwards from ground level so we will put the (- sign) in the answer

So answer will be -50.49meters
